A Summary of Design and Calculation of Tampered Pile
Yao Yonghua
1993, (1): 8-12.
[Abstract](43) [PDF 4975KB](7)
Abstract:
The tampered pile is a kind of piles technically advanced and economically rational. On the basis of relevant summary materials and large amounts of engineerig cases, the design of tampered pile and the calculation of its bearing capacity are dealt with herein. Several problems commonly concerned are discussed so as to promote the application of the tampered pile technique.
Study on Load Distribution of Pile and Surrounding Soils in Composite Ground Mixed with Cement in Depth
Guo Zhiye
1993, (1): 13-16.
[Abstract](20) [PDF 3915KB](7)
Abstract:
Based upon the results of load test for composite ground mixed with cement in depth, a study is carried out and there come the results that the stress ratio of the pile and surrounding soils is 3.2~5.2 and the load distribution on the pile and soils is 75~80% and 20~25%。The results have been verified by some engineering practice and may be used as a reference to the ground reinforcement with cement in depth.
Application of Pump Suction Reverse Circulation to Boring of Pile Foundation
Zhao Jiewei
1993, (1): 17-19,16.
[Abstract](24) [PDF 4158KB](6)
Abstract:
This paper, in the vien of engineering praetice researches,the application of hydraulic movement and drilling technology of pump suotion reverse circulation in pile basement, Which could gives experiences much helpful in such engineering cases.
A Method for Interpreting the Static Sounding Data by Computer
Di Junjing
1993, (1): 20-25.
[Abstract](25) [PDF 5731KB](7)
Abstract:
Based upon the theory of cubic spline function with second boundary condition and the method of optimum segmentation in the multiple-element statistical analysis, a software system is built up to process by micro-computer the static sounding data. The system can complete a series of tasks such as data interpreting, calculating and plotting with the Output of all the processing results in the form of charts. The concept of optimum segmentation is expounded with the emphasis on the application results of the system in the engineering practice.
The Constructive Method of Guand Fence Pillar and the Istallation of Wave—shaped Bream for Expressway
Chen Heming
1993, (1): 26-29,58.
[Abstract](34) [PDF 4996KB](4)
Abstract:
The canstructive method of guard fence pielar and the installation of wave-shaped bream for expressway is introduced in this paper. Boring machme YD-1 is used to hit pillar. Its various function are compeletely brought into play, Such as lightly and flexibly opera-ting, Conveniantlg installing component with construction,quickly shrfting anol high work efficiency. It has the internal advanced constmctive level.
Study on Test Accuracy of TM-85 Soil Density Gauge
Shao Huanrong
1993, (1): 30-32.
[Abstract](70) [PDF 2485KB](5)
Abstract:
In the soil test, it is found that T the content of clay particle taken from the TM-85 soil density gauge is 2-5% more than that obtained with the transfer pipet formerty used. Here four TM-85 gauges are studied one by one and corrected with regard to the reading, falling distances and curving surface, which may be a reference for colleagues.

Discussio on Several Formulations About Mathematical Modle of Three-Dimensional Flow
Sun Yong
1993, (1): 33-38.
[Abstract](17) [PDF 4928KB](5)
Abstract:
On the basis of analysis to the establishing Curse of differential a equation and enperience from actural application, a discussion is raised on the formulations about the mathematical model of 3-D flow. A new point of view is also put forward in this paper.
Plan Demonstration of Water Supply for 756 Plant
Zhao Zhibang
1993, (1): 39-44.
[Abstract](51) [PDF 5108KB](5)
Abstract:
Based upon the principle that when the distance between the draw well and its replenishment source, the influent stream,is mOre than 30 meters,the suspended matters,bacteria and partial chemical ions in the water will be filtered by the filter bed, it can be deduced that,replenished by either lateral influent stream or vertical perched water,the clean water will be obtained so long as it flows through a filter bed with a thickness more than 30 meters before it flows into the well. On the basis of this theory,the plan of waler supply for 756 plant is discussed herein.
