Numerical tests on the mechanism of the cushion in composite foundation;

According to the results of in-situ tests,the failure mechanism of composite foundation is mainly decided by the interaction between soil and cushion in the state of thick cushion or under embankments;and the practical bearing capacity of a pile in composite foundation is not brought into full play.

A cushion is installed under a pile cap, then the load is redistributed between the pile and soil.

According to the laboratory and in situ tests, this paper discusses into the roles Of the mattress of compositefoundtion with cement, fly-ask, gravel pile (CFGP), the bearing ratio of CFGP to soil under the vertical loads, and thedeformation behaviour of the compsite foundation.

Objective: To evaluate the effect of the hard bed and electric vented bedsore prevention mattress, which is to prevent the complicatedness of the malignant tumor complicated Superior Caval Syndrome(sccs) patient Methods: The 64 patients with malignant tumor complicated Superior Caval Syndrome(sccs) were randomized into two group.

The optimization of mattress layer in CFG pile composite foundation;

It introduces design method of handling compound foundation by low-strength concrete pile,puts forward fixed 5 parameters in design,narrates calculative process of compound foundation by low-strength concrete pile,and points out importance of mattress layer of compound foundation.
