Analysis on pile foundation technology of multistory building in soft soil area

Through one district project design practice,it makes the analysis and appraisal to get the compositing pile foundation design by using settlement control methods in soft soil area,discusses the common action principles of pile,soil,and cushion cap,to supply reference to the design of pile foundation in similar area after.

The paper desribes how to choose a reasonable supporting design and earth excavation plan for garanteeing not only safety and reasonable,but also ecenomic construction,com- bined with enginening practice,some problems in foundation pit supporting and earth excavation process in soft soil area are analysed and a lot of beneficial results h.

According to the factual data,the problem of soft soil settlement in the process of constructing the freeway is simulated with FLAC~(3D).

In this paper, a computation method for retaining structure of deep excavation in soft soil considering construction steps is put forward.

Design for deep excavation retaining in soft soil region;

How to control and deal with the displacement in soft soil region has become a very important problem.

The analysis shows that,the super-long piles in the soft clay area behave as typical friction piles,with the vertical bearing capacity being supplied mainly by side friction resistance, and that buckling stability analysis and s.

Environment effect and harm are introduced for deep foundation excavation in soft clay area.

In this paper, based on the experiment results, the characteristics of strength change of the soil in passive area and the effect of its retaining on the strength during excavation of foundation pit in soft clay area were analyzed.

In this article, authors introduce application of the new pile-network compound foundation technology, and analyze construction plan, construction method and matters need attention in construction of the pile-network compound foundation technology for deep and thick soft clay foundation treatment.

Based on the measurement in site, the change of pore water pressure in saturated soft clay foundation improved by dynamic drainage consolidation is analyzed and studied.
