高陡加筋边坡离心模型试验与数值分析

为实现增大堆场面积、减小弃方外运、美化港区环境、节约工程投资的目的,针对长江上游重庆果园港二期工程陆域堆场形成,提出采用37.5 m的高陡加筋边坡设计方案,通过离心模型试验与数值分析相结合的技术路线,分析和研究了现有2#和6#加筋边坡设计断面对应的有、无加筋边坡断面以及变换坡率、变换填料等条件下边坡的稳定性,优化设计和指导施工。

Centrifugal model test and numerical analysis of high and steep slope reinforced side slope

For the purpose of enlarging the area of the storage yard, reducing spoil transportation, beautifying the harbor environment, and cutting down the engineering cost, we propose the design scheme of 37.5 m tall high and steep slope reinforced side slope for the land formation in Chongqing Guoyuan port phase two project upstream the Yangtze River. Based on the centrifugal model test and numerical analysis, we analyze the stability of the existing No.2 and No.6 side slopes side slopes with and without reinforced slopes respectively and under the condition of slope rate variation and filling materials variation, so as to optimize the design and guide the construction.
