Analysis and research of the different of the plank thickness show the change of counterforce on the pile,the plate of the maximum flexibility and the flexibility disparity,the plate internal force.

Based on the mediumthickness plate theory,considering the interaction among upper structure,foundation and soil,also taking the nonlinear factor of soil into account,the three dimensional finite element method is used to analysis the deformation and internal force of raft plate below frametube.

The Load Sharing Function of the Raft in the Pile-raft Foundation and the Analysis on the Influencing Factors;

Experimental study to reduce differential settlements of raft of composite foundation with rigid piles;

Change characteristics of vertical displacement and its difference of raft in large pile-raft foundation;

Analysis and calculation of the joint action among raft plate, pile and foundation in one high-rise building;

Based on the analysis of the causes for thermal cracks produced in mass concrete,preventive measures were taken from aspects of raw & produced materials,admixtures and proper construction method,and the thermal cracks in foundation raft plates of high-rise building were controlled effectively.

The analysis and calculation of coaction between raft foundation,piles and ground for an expressway office;

Dynamic interaction between pile groups and raft foundations in axial vibration

The longitudinal whole bending of long narrow hybrid structure with raft foundations and a few longitudinal-cross walls should not be neglected.
