盐渍土地基中单桩和群桩的竖向承载性能试验研究
Experimental study on vertical bearing behavior of single pile and pile groups in saline soil ground
摘要
Abstract
To study the vertical bearing behavior of single pile and pile groups in layered saline soil foundations,laboratory reduced-scale model tests including models of a single pile,two piles,four piles and six piles in saline soil foundations with different salt contents are carried out.Through model tests,the Q-S curves,stiffness and group pile efficiency of single pile and pile groups are obtained.The effects of the salt content of saline soil on the interaction of pile groups are analyzed.The stiffness and pile group efficiency coefficients obtained from the tests are compared with the existing theoretical calculation value verifing the correctness of the test results.It is found that the variation in salt content has no obvious effect on the Q-S curves of single pile and are pile groups.There is interaction between piles,but the stiffness of pile groups and a single pile is not in a multiple relationship.The pile group effect decreases with an increasing number of piles.关键词
