摘要
高陡顺层岩质边坡治理及其支护设计是边坡设计难题之一,在边坡施工设计中,对于边坡失稳范围的确定一直是一个重要的问题,本文结合巴马—凭祥公路巴马至田东段工程边坡工程,采用控制变量法推导边坡的失稳范围公式,并实地测量相关数据,运用所推公式计算临界长度,将所得结果与实际边坡滑坡情况进行对比,调查资料验证其合理性。失稳破坏临界长度的确定为边坡后续的稳定性计算和支挡工程设计提供了依据,达到了预期目的。因此,笔者的分析方法对具有类似特点的顺层边坡具有借鉴价值,并为相关工程提供参考依据。
The treatment and support design of high steep bedding rock slope is one of the difficult problems in slope design.In the slope construction design,it is always an important problem to determine the slope instability range.Combined with the slope engineering of the east section of Bama-Pingxiang Highway from Bama to Tiandong,this paper deduces the formula for the instability range of the slope by using the control variable method,measures the relevant data on the spot,calculates the critical length by using the formula,compares the results with the actual slope landslide,and verifies its rationality by investigating the data.The determination of the critical length of instability failure provides a basis for the subsequent stability calculation of the slope and the design of the retaining works,and achieves the expected purpose.Therefore,the author's analysis method has reference value for bedding slope with similar characteristics,and provides reference for related projects.
