一、引言 行走土壤力学的基本观念,是在土壤力学与塑性理论的基础上建立的。它从系统观点,将土壤参数与机车参数组成数理方程。1917年贝士坦提出压力是沉陷的函数;1944年万谷朔维根据库仑的土壤剪切破坏规律,在接地压力均布的设想下,提出了推进力与土壤参数的方程。同年,培克也根据这个理论,将前述基本公式研究发展成普遍应用式。并且提出了式中必须测定的土壤的七个基本参数:垂直载荷的有K_c—内聚力模数,K_φ—内摩擦角模数,n—沉陷指数;平面剪切的有φ—内摩擦角;C—内聚力,K_1、K_2—打滑参数。1949年加博历的工作,得到与培克相同见解。此后,经过很多的研究,使行走土壤力学研究的发展,逐步巩固。
I. Introduction The basic concepts of walking soil mechanics are based on the theories of soil mechanics and plasticity. It from the system point of view, the soil parameters and locomotive parameters form a mathematical equation. In 1917 Beitin proposed that pressure is a function of subsidence. In 1944, according to Coulomb’s law of soil shearing and failure, under the assumption of uniform earth pressure, Propagation equation was proposed for propulsion and soil parameters. In the same year Peck also developed the above basic formula research into a universal application according to this theory. In addition, seven basic parameters of soils must be determined: K_c-Cohesion Modulus, K_φ-Internal Frictional Angle Modulus, n-Depression Index for Vertical Load; φ-Internal Friction Angle for Plane Shear; C - cohesion, K_1, K_2 - slip parameters. The work of Gabriel in 1949 gained the same view as Peck. Since then, after a lot of research, so that the development of walking soil mechanics research and gradually consolidate.
