摘要
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 ground water on slope stability were described in detail, the ground water causes erosion to the slope surface, and effects of ground water include hydrostatic pressure, dynamic water power and chemical corrosion. The Bishop＇ s simplified method of slice for slope stability calculation was introduced, and based on this, the calculation method for slopestability in consideration of ground water was obtained. Finally, in combination with engineering practice, it waspointed out that reliable and effective drainage system should be installed in accordance with different slope characteristics in slope control, and at the same time, plant protection should be set up to increase the slope stability.
