This paper analyzes relations between in soil depth of vibrating sinking cast in place pipe and foundation soil strength, puts forward the formulas of calculation, and provides theoretical basis for design and construction.

Checking the foundation strength by using the standard method;

It introduces the treatment principle and scheme,and does analysis calculation to the raft plate settlement and the spring rate of bottom soil,pile top settlement and the rigidity of pile body,foundation strength,which will supply reference to the similar projects.

Construction show reinforcement treatment can acquire stable foundation strength and good ground endurance.

The influence of the shape and size of footing on bearing capacity of geofabric reinforced soils

The v alue of land use intensity must be beyond the extent of minimal limited conditio ns.

By means of high-precision satellite image, field survey, GIS and statistics, this paper analyzes the land use intensity of Lanzhou, its spa-tial distribution as well as the drive forces of industry by two index i.

The purpose of this study is to analyze the formation of spatial structure of urban land use intensity in Beijing,and reveal its characteristics as well as influencing factors,verify and develop spatial structure theory in city economics.
