By performing the design test on representative full-scale foundations of KD section according to specification of IEC1773,it is proved that the designed foundations in the Nigerian KDA transmission line project can meet the requirements of NEPA specification and IEC 1773 specification.

Simulation of influence of biggish pile shoe pulling out on foundation of bucket foundation platform with finite element program;

Analysis of clay soil softening in ice-induced vibration of bucket foundation platform;

Dynamic physical parameter model of bucket foundation suction penetrqtion;

Analysis of the interaction between the bucket foundation structure and the soil on the basis of time domain;

A linear coupling analysis of infinite element, finite element and contact element of the interaction between bucket foundation and groundsill;

Model tests on horizontal cyclic bearing capacity of bucket foundations in soft clays;

Based on a project of complex foundation containing deep weak underlying,some foundation treatment measures are analyzed and the measure of cooperative work between replacement cushion and box foundation is put forward.

The current criterion doesn’t consider the effect of supporting structure in computing the box foundation settlement, which makes the error between academic settlement and practical settlement.

Due to the temperature stress produced by hydration heat and the shrinkage of the concrete proper, the bulky concrete box foundation is liable to hazardous crack under inadequate design and construction.

By analysing the foundation style selection of a small-tall building at soft subgrade foundation soils,this paper focuses on the application and selection principles of pile foundation & raft foundation.
