摘要
路基沉降的精准计算一直是工程界关注的热点问题。为了更加精确的计算路基地基土的沉降值,基于简化的Pastor-Zienkiewicz模型和分层总和法的基本理论,推导了路基下地基土的变形计算方法。针对平湖路基工程,对勘测深度内处理后的地基土进行变形计算分析,计算结果表明:勘测深度内总变形量为15.13 mm。该计算方法可一次性计算平面所有点的变形值,且计算结果能够在三维坐标系直观表示。该计算方法可为路基变形计算和后续的变形控制提供一定的参考依据。
The precise calculation of subgrade deformation is a hot topic in engineering. In this paper in order to more accurately calculate the settlement of subgrade foundation soil, based on the simplified Pastor-Zienkiewicz model and the basic theory of layer-wise summation method, the deformation calculation method of foundation soil under subgrade was derived. For the subgrade engineering in Pinghu, the analysis of deformation calculation for multilayered foundation soils under treated subgrade was done in drilling depth. It is shown that the total deformation is 15.13 mm for the treated subgrade. And this calculation method can calculate all points of calculation plane by one-time. And the calculation results can be visual represented in a three-dimensional coordinate system. The calculation method can be used for the deformation calculation of foundation soils under subgrade and provide references to deformation control.
