本文简要的介绍了开挖及岸坡工程的孔隙压力变化及边坡变形的规律。文中以国内外的工程实例说明,对施工末期稳定问题,可用φ=0法,但使用时,要十分慎重,对使用期稳定问题宜采用有效应力分析法。大量工程实例表明,毕肖普(Bishop)稳定分析法是一种较好的方法,可获得满意的成果。最后,介绍了我所使用方法的历史演变过程及将来发展的可能途径。
This paper briefly introduces the pore pressure changes and the law of slope deformation in excavation and bank slope engineering. In the paper, domestic and foreign engineering examples show that for the stability of the end of construction, φ=0 method can be used, but when used, it should be very cautious, and effective stress analysis method should be adopted for the stability of the use period. A large number of engineering examples show that the Bishop stability analysis method is a better method and can achieve satisfactory results. Finally, I introduced the historical evolution of the methods I use and possible future developments.
