Abstract:
Discussed the Columb-Rankine theory and its limitations, calculating separately and combined for soil-watet pressure, the relationship between soil-water pressure and retaining structure, the effect on soil pressure of soil property. And simply discussed tbe problem of concept design of geotechnical engineering.

Abstract:
The stability and de formation is tne two most important problems in the design of deep foundation pit. Introduces the unstable form of slope, gravity rataining wall, cantilever sheet pile wall,single anchored or propped cantileret wall, multi-ancnored or propped wall and soil nail wall, etc.And introduces varions calculating methods for failure. And gives the method to estimate the deformation of the surtounding surface around the foundation pit.

Abstract:
One of the key problems of the deep foundation pit of tall building in Wuhan is that the seepage failute often occures in the thick artesian sandy aquifer in Hankou area. Such as water leaking and sand falling in the wall, soil flowing and step blowing in the bottom. They endangers the safety of the pit and leads to failute of environment. Mainly introduces the hydrogeological conditions and tne characteristics of groundwater seepaging net in foundation pit in this area. And discusses the selection of groundwater prevention method, the relationship between support and water-stopping structure and the calculation about the surface subsidence due to dewatering.

Abstract:
Soil nailing is a technique of insitu ground reinforcement that is bonded to surrounding ground to form combined unit. Its effect is similar to a gravity retaining wall. According to test results combined with engineering cases and monitoring, the principle of soil nailing wall, the calculation of its stability, the choice of its design parameter and installation are illustrated. The structure system may be used for supporting a temporary deep foundation pit and stabilizing a permanent slope. Monitoring of tlie soil nailing wall have showed that as a supporting system, the performence of the technique is reliable, economical and fastish. The author believes this technique will have a wide landscape of development in the future.

Abstract:
Analyses the deformation mechanism of the pour landslide in the W200-W600 area of the north wall of Fushun west open pit with FLAC program of FEM for large deformation. Evaluates the effect of anti-slide pile and dewatering, provides the technical guidance and basis for engineeting design of slope treatment.
