  1. 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

    論文第二章為凍土斷裂力學的基本理論,包括斷裂力學在凍土研究中的工程適用性、條件適用性、平面應變斷裂韌度測試的適用條件等,給出了凍土斷裂韌度k _ ( c ) 、 k _ ( c ) 、 -型復合斷裂測試的基本原理及試驗方法,並基於weibull脆性破壞理論推導了凍土三點彎曲試樣k _ ( c )尺寸效應系數,為後面的工作提供理論基礎。
