摘要
推出了大气张力抗拉强度通用公式,土的抗拉强度由真抗拉强度、水气不抵大气压强抗拉强度、表面张力贡献抗拉强度组成。推出了大气张力库仑抗剪强度公式,形式与库仑定律相同,但含义比库仑定律扩大和具体化。对于粘土,随着含水量的减少,土的抗拉强度增大,使真凝聚力和初始摩擦抗剪强度增大,总的明显加大初始抗剪强度。
This paper introduced the atmosphere tension tensile strength general formula. Tensile strength of soil consists of the true tensile strength, tensile strength of water and gas do not cover the atmospheric pressure, tensile strength of surface tension contribution. This paper introduced the tension atmosphere coulomb＇s formula of shear strength, form the same as the coulomb＇s law, but bigger than coulomb＇s law and specific meaning. For clay, according as the decreasing of water content, the tensile strength of soil increased, make true cohesion and initial friction shear strength increases, the total initial shear strength increased obviously.
