地基稳定性是设计中的重要课题之一,而土体的抗剪强度又直接地影响地基的稳定性。但是,究竟基础下哪一部分深度土层对它的影响最大,这就是工程地质钻探中取土样的核心问题。为此,对地基抗剪试验土样就其深度进行初步探讨。一、均质土层抗剪试验取土深度目前,土样取法存在一定问题,即每钻1～2m 取一土样,测出土样的抗剪强度及其它土的物理指标,没把土体滑动破坏时受剪
Foundation stability is one of the important topics in design, and the shear strength of soil directly affects the stability of the foundation. However, what part of the underlying soil layer has the greatest impact on it, which is the core problem of soil sampling in engineering geological drilling. For this reason, the depth of soil samples for ground shear tests is initially discussed. First, the homogenous soil shear test depth of soil extraction At present, there are certain problems in the soil sampling method, that is, every drill 1 ~ 2m to take a soil sample, measure the shear strength of soil samples and other soil physical indicators, did not put the soil Shearing when sliding
