摘要
针对岩土工程遇到容易混淆的问题,如岩土指标是否都可以采用地区经验值、基底附加应力与地基净反力是否相等、分层土层的平均指标是否都可以按厚度加权处理、流砂与液化的本质是否相同、减压平台越靠近挡土墙底部减压效果是否越好等,分别探讨了各种错误说法的原因,给出了正确概念及取值计算的原则和方法。
This paper presents the author＇s considerations on several parameters and concepts that are commonly misused by the practitioners.These parameters/concepts are：index properties for design can be selected from the local practice;difference between the net additional effective stress and the footing pressure;design parameters for layered soil can be taken from the layer thickness weighted average;the mechanism of the quick sand is essential the same as the liquefaction;the relief platform should be close the bottom of the retaining wall.The paper presents the correct parameters and concepts.
