一、前言目前国内常用标准贯入试验方法确定砂类土地基的容许承载力。不仅如此,在我国的“抗震规范TJ11-78”中也规定用它来判断砂类土地基是否液化。由此可见这种原位测试方法在工程勘察中所起的重要作用。但使用中在操作方法上还欠统一,致使测得的N_(63.5)值离散度大,可靠性差,缺乏可比性。给正确评价砂类土地基带来困难。本文结合工程实践,对用动力触探评价砂类土地基谈几点看法,同时也将介绍一些 I. INTRODUCTION At present, the commonly used standard penetration test methods in China determine the allowable bearing capacity of sand-based ground. Not only that, but also in China’s “TJ11-78” seismic code, it is also stipulated that it can be used to judge whether the sand ground is liquefied. This shows that this in-situ test method plays an important role in the engineering survey. However, the method of operation still lags behind in use, resulting in large dispersion of measured N_(63.5) values, poor reliability, and lack of comparability. It is difficult to correctly evaluate sand foundations. This article combines engineering practice to discuss several points of view on the use of dynamic penetrators to evaluate sand lands.
