摘要
综合考虑了沿河路基受冲刷边坡几何形态变化、河道水位及地下水位对公路路基稳定性的影响情况,建立了沿河路基冲刷崩塌理论模式,并通过对工程实例进行计算分析,探讨了各因素对沿河路基边坡稳定性的影响规律,提出了沿河路基边坡稳定性的判定方法,可作为沿河路基设计与施工的有益参考。
Through comprehensively considering the several factors affecting the slope stability of riverain subgrade, such as the scoured slope's geometric patterns, the river surface and underground water level and so on, the theoretical mode of scouring collapse for highway subgrade by river is established, and the affecting regulation on slope stability is discussed by calculation and analysis for an engineering example. At the same time, the method for judging the slope stability is put forward. All these could give some benefitial references for the design and construction of riverain highway subgrade.
