TIME EFFECT ON BEARING CAPACITY OF SINGLE CEMENT SOIL PILE
粉喷桩单桩承载力的时效分析

Using elasto-plastic model and elastic mechanics theory,the stress transfer and deformation of pile along the pile are analysed respectively. The calculation model of single pile is built and the theoretic solutions are gained. The increase of bearing capacity of single pile is obvious with time. According to the data of static loading test for single cement soil pile,the time effect on bearing capacity of single cement soil pile is analysed in the saturated soil. The influences of groundwater on the bearing capacity are considered too. The presented results are of important significance to optimizing design of the cement soil pile composite foundation and deciding the time of the loading test.
