本文基于应力水平相等时,固结不排水剪的可能体变与固结排水剪的体变相同的假设,简述了静荷剪切过程.中孔隙水压力产生的机理及其计算方法。针对斯肯普顿孔压计算方法的不足,提出在全应力应变范围内计算孔隙水压力系数 A 的方法。几种方法应用比较表明,本文所提出的方法物理意义明确,结果也相当接近实测值。 In this paper, based on the assumption that stress levels are equal, the possible volume change of consolidated undrained shear is the same as that of consolidated drainage shears, and the mechanism of the pore water pressure generation and its calculation method are described briefly. Aiming at the shortcomings of the Skonton pore pressure calculation method, the method of calculating the pore water pressure coefficient A in the whole stress-strain range was proposed. The comparison of several methods shows that the proposed method has a clear physical meaning and the results are quite close to the measured values.
