摘要
为了避免边坡设计时加固不足导致后期发生灾害或加固过度造成投资浪费,以省道221线大埔段改造工程为例,根据详勘结果及土工试验数据,采用迈达斯SoilWorks软件建立数值模型,定量计算并分析深挖路堑加固前正常工况和暴雨工况的稳定性,针对加固前潜在的滑动面、最大剪切应力、土体总位移等数据,拟定加固方案,为类似边坡工程的加固处治提供技术思路。
In order to prevent investmentwaste due to later disasters from insufficient reinforcing or over reinforcing by side slope design, taking DaPuSection Reconstruction Project of Provincial Highway No.221 as an example, being based on detailed survey results and test data, a numerical model has been establishedusing Midas SoilWorks software. The quantitative calculation and analysis on deep digging cutting in strengthening the stability of normal condition and heavy rain conditions have been conducted. According to the calculation results of potential sliding surface, maximum shear stress and total displacement of soil before reinforcement, the reinforcement scheme has been proposed, which can provide reference for similar side slope projects.
