| 摘 要： | 基于边坡稳定性分析理论,提出一种管道井式穿越黄土冲沟边坡确定设计参数的新方法.该方法首先通过对边坡稳定性进行分析,寻找出边坡潜在最危险滑动面的形状及位置,然后由此结果确定管道斜井或竖井的安全井口位置、井长或井深、水平巷道长度和斜井极限倾角等设计参数,并给出井口与边坡坡肩安全距离、斜井倾角、井长等设计参数的计算公式.研究结果表明:只要管道穿越斜井或竖井布设在边坡潜在最危险滑动面之外,并充分考虑施工影响,则管道工程的施工时边坡的稳定性影响较小;新方法简捷实用,可用于油气管线穿越各类土质边坡或冲沟时确定设计参数.

| Abstract: | Based on the stability analysis theory of slope,a new method of determining design parameters for traversing the loess gully or slope in pipeline well was presented. In the method,the stability analysis was firstly carried out to find the shape and the position of the potential dangerous sliding surface of slope. Then the design parameters of inclined or vertical pipeline well,such as the safety cut,the length or depth and the limit obliquity of well and the length of horizontal opening,were determined.
