Prevention of the crack on raft foundation concrete;

A method of topology optimization of grillage structure with stress constraints is presented and applied to analyze the reinforced beam of raft foundation.

Improvement of design method for pile raft foundation and its economical significance;

In order to study the interaction of upper structure,pile raft foundation and soil,a modle of three dimensional finite element analysis is established.

The paper has a study on properties of pile raft foundation for high buildings based on test.

Analysis and correction of raft foundation caculation on PKPM;

Construction Technique for Mass Concrete of a Tall Building s Raft Foundation;

Design, Construction and Inspection for A tall building Raft foundation;

An interaction factor approach and parametric analysis for piled raft foundation;

Analysis of interaction mechanism of piled raft foundation by use of simplified nonlinear model;

General analysis method of piled raft foundation under vertical loading;

Application of large concrete mat foundation is less interiorly.

This manuscript has done research on the computation methods of the mat foundation with the interactive principles of soil and base.

It is difficult to find out the suitable solution to mat foundation based on elastic body in civil structural designing because it is influenced by both upper structure and building foundation.

The large scale model test proves that the rigidity of frame structure with large thick raft foundation is approximately equal to the rigidity of box foundation.
