详细论述了地表水和地下水对边坡稳定性的影响,地表水主要对坡面产生侵蚀作用,地下水的影响包括静水压力,动水力和化学溶蚀作用。介绍了边坡稳定性计算的毕肖普条分法,在此基础上得到考虑地下水影响时边坡稳定性的计算方法。最后结合工程实例,指出在边坡防治中应根据不同边坡的特点,设置可靠有效的排水系统,同时采取植被防护,以提高边坡的稳定性。
The effects of surface water and groundwater on slope stability are discussed in detail. Surface water mainly causes erosion on the slope. The effects of groundwater include hydrostatic pressure, hydrodynamic and chemical dissolution. The Bishop method for slope stability calculation is introduced. On this basis, the calculation method of slope stability considering groundwater influence is obtained. Finally, combining with engineering examples, it is pointed out that a reliable and effective drainage system should be set according to the characteristics of different slopes in slope prevention and control, and vegetation protection should be adopted to improve slope stability.
