| 摘 要： | 结合现场试验,对真空预压法和堆载预压法的加固效果进行了对比研究.试验过程中两种方法的等效荷载大致相同,监测结果表明,真空预压法和堆载预压法在本研究中的最大表面沉降相差不大,两种方法造成的地基侧向变形方向相反,堆载预压水平位移幅度大于真空预压,堆载预压法的有效加固深度要大于真空预压法,加固后土体强度的提高程度两者相近.在...

| Abstract: | According to the field tests for the vacuum preloading method and load-accumulated preloading method,the reinforcement effects of two methods are compared and studied.In the tests,two test areas have the roughly same equivalent load.The monitoring results show that two test areas have very small difference between the maximum surface settlement,and two methods result in the opposite direction of the foundation's lateral deformation,in addition,the horizontal displacement and effective reinforcement depth of... |
