摘要
简要介绍扁铲侧胀试验(DMT)的基本原理及一些应用成果,并将其应用于天津滨海新区软土的研究。结果表明:DMT对天津滨海新区的正常固结软土划分合理,但对吹填软土划分不够准确;DMT对应力历史的描述除粉土外符合实际情况;天津滨海新区扁铲土性指数ID值在0.3左右的软土的静止侧压力系数K0值为0.65,且真空预压将导致K0值变大。
The flat dilatometer test (DMT) theory and some application results are briefly introduced. DMT is used to study soft soil of the New Coastal Area of Tianjin. The results indicate that soil stratification for normal con-solidation clay is accurate, but not suitable for soft dredger soil. The description of stress history accords with the fact except silt. The lateral earth pressure coefficientK0 is 0.65 for soft soil of whichID is 0.3, and increases along with vacuum preloading.
