In the first part of this dissertation , theory of fracture mechanics of the frozen soil has been presented . a general strength theory based on fracture mechanics was proposed , and the validity of the theory using in frozen soil was discussed . the fracture toughness values for different kinds of cracks extension were determined , such as the plane strain fracture toughness for mode i cracking ( kic ) , fracture toughness for mode cracking of frozen soil and the intersection of frozen soil and concrete
论文第二章为冻土断裂力学的基本理论，包括断裂力学在冻土研究中的工程适用性、条件适用性、平面应变断裂韧度测试的适用条件等，给出了冻土断裂韧度k _ ( c ) 、 k _ ( c ) 、 -型复合断裂测试的基本原理及试验方法，并基于weibull脆性破坏理论推导了冻土三点弯曲试样k _ ( c )尺寸效应系数，为后面的工作提供理论基础。
