【摘要】:對重慶地區(qū)最常見的泥巖采用邊坡穩(wěn)定性分析中的圖表法,簡明地分析確定了泥巖的極限坡率。得出了微風化泥巖,坡高在50m以內,其極限放坡系數(shù)可以為1∶0——極限坡率=∞,也就是不放坡,垂直開挖的結論。應用此結論,解決了墊江縣迎春河涵洞的開挖過程中,受場地限制無法達到設計放坡系數(shù)的實際問題,節(jié)省了工程造價、縮短了施工工期;還解決了墊江縣桂西大道修建過程中兩邊征地不足,無法滿足設計放坡系數(shù)的問題,節(jié)省了工程造價、減少了土地占用。
[Abstract]:In this paper, the most common mudstone in Chongqing area is analyzed and the limit slope ratio of mudstone is determined by using the chart method of slope stability analysis. The conclusion that the slope height is less than 50m and the limit slope coefficient can be 1: 0- limit slope ratio = 鈭,
