关于岩质边坡计算中的参数选用探讨

阮铁锋

摘要:

道路设计过程中，不可避免会遇到边坡设计，其中挖方边坡是边坡设计的重点，也是难点。设计人员在进行挖方边坡设计时候，往往不加分析直接采用地勘提供的参数，而实际上，岩层并非是均质层，是自上而下的连续变化层，设计直接套用地勘提供的参数，显然是不严谨的，必然会导致计算结果与实际情况出现偏差。本文以一般自然山体为研究对象，从分析岩层性质出发，通过细化分层并结合实际工程案例进行计算比较，提出相关的计算建议，供广大从业人员参考。

Abstract:

Slope design is common in road design, in which excavation slope is key and difficult points.Slope designers usually use the parameters survey unit provided without analysis. In fact, rock stratum is homogeneous but has continuous change from the top down.It’s not precise for slope designers to use directly the parameters survey unit provided,which will leads to deviations between the results and the facts. This paper, object with general natural mountains，through hierarchical analysis of the character of rock stratum, based on results comparison of real projects, presents some proposals of rock slope calculation, and provides a useful reference for other engineers.
