本文的目的,是从理论上和实验上发展双冲压(剪)试验应用于粘性土。这种发展包括:(a)根据完全塑性理论导出一个可以计算土的抗拉强度的方程式;(b)导出一个抗拉强度与环境变量之间的基本关系式;(c)将采用双冲压试验和拉断(裂)试验的各种材料,包括混凝土、沙浆和沥青混凝土所测定的抗拉强度的结果加以比较。 The purpose of this paper is to develop double-press (shear) tests both theoretically and experimentally on cohesive soils. This development includes: (a) Deriving an equation based on complete plasticity theory that can calculate the tensile strength of soils; (b) Deriving a basic relationship between tensile strength and environmental variables; (c) And the tensile (crack) test a variety of materials, including concrete, mortar and asphalt concrete tensile strength of the results were compared.
