1.本文分析了前人关于饱和粘土的抗剪强度与含水量、有效应力之间的关系的试验资料以后,认为Henkel(1959、1960年)用两个粘粒含量较高的重塑饱和试样,所获得的强度规律特性的结论,也适用于原状的饱和软粘土。 2.由此观点出发,本文阐述了荷重作用下土体从开始固结至最后破裂的过程,从而提出了荷重作用下土的抗剪强度的估算方法,即含水量法。本法乃是利用饱和粘土的含水量与有效应力之间存在的规律,以代替有效应力法中所寻求的当土体处在极限平衡状态时剪切面上的总压力σ_f及相应的孔隙压力u_f。
1. After analyzing the previous experimental data on the relationship between shear strength, water content, and effective stress of saturated clays, Henkel (1959, 1960) considered that the remolding saturation test with high content of two clay particles was used. The conclusion of the obtained strength regularity also applies to the undisturbed saturated soft clay. 2. From this point of view, this article describes the process of the soil consolidation from the initial consolidation to the final breakdown under the action of the load, and puts forward the estimation method of the shear strength of the soil under the load, ie the water content method. This method uses the law existing between the water content and the effective stress of the saturated clay to replace the total pressure σ_f and the corresponding pore pressure on the shear surface when the soil is in the limit equilibrium state sought in the effective stress method.
