| 摘 要： | 文山—辰山公路位于福建连江可门港区,环罗源湾,其中K5+000~K5+140段沿线穿越工程地质条件复杂的岩质高边坡。该边坡岩体发育有2组优势结构面,边坡受到该2组优势结构面的共同作用,需评价其稳定性。运用赤平极射投影方法,分析判定了斜坡自然状态的稳定性,并进一步分析得到拟开挖路堑边坡的合理放坡坡率。现经施工实践证明,效果良好。

| Abstract: | Whenshan-Chenshan highway is located in Kemen Port in Lianjiang, Fujian province, surrounding Luoyuan Bay, and there is a high rock slope, with a complicated engineering geological condition, to be crossed in the segment of K5+000~K5+140. There are two sets of dominant structural plane developed in the high slope rock mass, and stability of the slope is influenced by them both. Therefore, it is necessary to evaluate the stability. By Stereographic projection, the stability of the natural slope is analyzed. Furthermore, to approach a reasonable slope ratio for excavation, the method is used again. After the cut slope is excavated, the effect is proved to be perfect. |
