Abstract: Combined with the actual situation of engineering investigation, the characteristics of core pipe drilling, threaded drilling, three-wing drilling and impact drilling, such as adapted strata, the drilling process, disturbance and destruction to soil, operation procedure, were analyzed. The advantage...
Abstract: A project in Beijing CBD has a foundation pit depth of 36 meters. Due to space limitations, a “two walls integration”+internal support system was adopted to achieve the functions of retaining soil and water in the foundation pit, while completing the construction of the exterior wall of the undergro...
Abstract: During close-spaced tunnel construction passing through existing bridge piles, and based on the field measured data, the change rules of bridge pile settlement, the settlement proportion of each stage, the distribution of soft strata in the tunnel body, and the impact of sleeve valve pipe driving me...
Abstract: The application of Kalman filtering in denoising static leveling and fixed inclinometer raw data was investigated. The results indicated that under slow deformation conditions, Kalman filtering can effectively filter out noise in the original data, provide reliable results, and reveal the true defor...
Abstract: River crossing construction of shield tunneling causes loss of soil mass and settlement of surface and upper bridges. Based on a shield construction project with river crossing construction in a muddy soft soil area, the ground and bridge pier settlement characteristics caused by river crossing cons...
Abstract: The large-angle cable-stayed pile support structure can save space outside the pit, has advantages such as convenient construction and low cost, and is suitable for scenarios where the anchoring space outside the pit is limited. To further study its deformation and stress mechanism, typical medium-d...
Abstract: A riverbank foundation pit utilized a triaxial cement-soil mixed wall for water seepage prevention. During excavation, water gushing, sand effusion, and seepage destruction occurred. After several unsuccessful attempts at sealing and remediation, a combined technique of dual-liquid grouting with jet...
Abstract: During the construction period, it is necessary to ensure that the existing railway transportation line that originally passed through here was not affected. The project of Fengtai station reconstruction was divided into three phases of construction, and construction was carried out in two phases in...
Abstract: A Class II residential land project in Daxing District, Beijing is surrounded by multiple high-rise residential buildings and an underground parking garage. To eliminate the adverse effects of differential settlement, multiple post-cast strips were installed. The existence of post-cast strips seriou...
Abstract: Combined with a foundation pit project in Kunming, numerical modeling was established using finite element software MIDAS GTS. Three numerical simulations were carried out on the surface settlement of the foundation pit and deformation of the neighboring buildings, including no buildings in the surr...
Abstract: The bearing capacity of post grouting piles in deep soft soil layers is influenced by multiple factors. Taking three sets of post grouting piles at the pile end of a certain project in Shanghai as the research object, the influencing factors on the bearing capacity of post grouting piles were invest...
Abstract: To study the dynamic and static responses of existing railway bridge piers under the influence of percussion drilling, the theoretical analysis, numerical simulation, and field test of the influence of percussion drilling on railway bridge piers were carried out. The theoretical analyses show that t...
Abstract: Nujiang airport is located in the high intensity seismic mountainous area in the southwest of China.The stability of the slope under the high fill load and seismic load is the key factor restricting the airport construction. The methods of theoretical analysis and numerical simulation were used to a...
Abstract: A deep foundation pit is situated in the flood plain of Nanjing. The geological condition is that the flowing plastic mucky silty clay is distributed in the upper part, and a deep gravel layer with high permeability and strong bearing ability is distributed in the lower part. The foundation pit is a...
Abstract: The landslide disasters in the north and south mountain areas of Tianshui are extremely developed, and it is extremely challenging to build roads in this area. Taking the analysis and remediation of a large tractive deposit landslide in Quping village, Tianshui as an example, engineering geological ...
Abstract: The layout of deep buried tunnels and the stability of surrounding rocks are closely related to ground stress conditions. The hydraulic fracturing method is a widely used and mature in-situ stress testing method for deep-buried tunnels. The hydraulic fracturing method was used to test the in-situ gr...
Abstract: Based on the spatial distribution characteristics of karst, the horizontal uneven distribution and vertical zonation characteristics of karst were summarized, and their impact on karst rate statistics was analyzed. Based on the investigation data of a buried sewage plant, the vertical zonation of vo...
Abstract: The engineering risks that may arise from geological conditions mainly include safety risks, quality risks, construction period risks, environmental risks, and investment risks. Geotechnical engineering survey documents should focus on safety and quality risks. The construction methods and procedure...
Abstract: Taking a railway tunnel entrance slope construction site as an example, the slope safety factor at different tunnel entrance elevation, different conditions (slope not excavated, excavation not loaded, loading after excavation), different conditions (natural conditions, rainstorm conditions, earthqu...
Abstract: The underground hidden karst developed in the limestone area has brought great safety hazards to urban engineering construction. Conventional geophysical prospecting methods are difficult to meet the high-precision detection requirements of urban engineering for karst diseases. This research introdu...
Abstract: Particle gradation is one of the main factors that affect the mechanical properties of rock-fill materials. To study the mechanical properties and deformation characteristics of the rock-fill materials with single particle size, the large-scale triaxial test and numerical simulation of particle flow...
Abstract: The commonly used technology of bored piles in sand and pebble fields is mud protection wall rotary excavation or reverse circulation drilling technology. This type of drilling technology requires a large amount of mud and high-quality control, which is prone to quality problems such as collapse and...
