地基承载力评价方法探讨

Research on evaluating ways of soil foundation bearing capacity

室内土工压缩试验一般仅用来评价土的变形性能 ,它作为土这种特殊材料———土的力学试验 ,应可用来评价土的强度性能。对e—p压缩曲线进行一系列坐标变换及计算 ,得到s—lgp曲线 ,然后根据该曲线上转折点估计土的承载力。此法简单易行 ,为评价地基承载力提供了一条新的途径。

Indoor soil mechanics compression test can evaluate not only soil's deformation performance but also strength performance.We can get S-lgp curve by transformation of coordinates to e-p compression curve,and then estimate the soil's bearing capacity according to the turning points on the S-lgp curve.The method is simple and easy to use,it supplys a new way of evaluaing soil bearing capacity.
