| 摘 要： | 高液限土是一种对工程有害的特殊土。为了处治高液限土地基,对室内土工离心模型试验进行分析,利用离心机产生离心力场,提高模型土体的体积力,形成人工重力。模拟高液限土地基在碎石桩处理后的固结性状,观测地基模型的变形和沉降。试验结果表明,碎石桩复合地基措施确实能改善地基的受力和变形性状,极大增强地基的稳定性。

| Abstract: | High liquid limit soil is a special kind of soil which is harmful to the engineering.In order to dispose the foundation of the high liquid limit soil,a centrifugal model test has been chosen,which uses the centrifugal power brought by centrifugal machine to improve the bulk power of the model and to form the man made gravity.The consolidation state of high liquid limit soil after the gravel pile is simulated,and meanwhile the deformation and subsidence of foundation model is observed.Through analysis of cen... |
