  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。
  2. The strength of frozen soil will decrease obviously if it is thawed, especially when ice lens is abundant in it, which is the main cause of the mud pumping in subgrade as well as the instability of foundation in seasonal frozen ground regions

    摘要凍土，特別是含冰透鏡體的凍土解凍時，出現強度大幅度下降的弱化現象，這是季節凍土區內路基春季翻漿冒泥、地基失穩的重要原因。
  3. Through surveying and analysis by synthesis of the environment of qingzang highway and the damage condition of the highway ' s base course, this paper take experiments of the key performances of the atsm, discusses the standards of control indexes of atsm for base courses in perennially frozen zone. by all the results of such experiments, a conclusion is obtained that the strength and all the pavement performances properties of the atsm are good enough to be used to build the base course of highway in perennially frozen soil zone

    寒區半剛性基層強度較難形成，而形成板體的基層又大多出現嚴重的反射裂縫，影響了使用性能，因此，本文通過調查與分析青藏公路的自然條件和路面基層及面層的損壞狀況，對基層瀝青穩定碎石的強度、低溫抗裂、疲勞以及抗凍等各項路用性能進行了試驗研究，探討了多年凍土地區基層混合料的關鍵路用性能的各項指標。
  4. In order to find out the mechanism of the soil strength weakening during the period of thawing and the effective prevention measures, some adjustment was made on the traditional triaxial apparatus, together with special frozen soil samples preparation equipment, customized frozen soil samples thawing apparatus and external heat preservation facilities, a new apparatus for investigating the weakening characteristic of frozen soil was made successfully

    為探明路基土融化過程中的強度弱化機理，在此基礎上制定有效的凍害預防措施，對國產土工靜力三軸儀進行了一系列改造，並配以專用的凍土試樣制備設備、凍土試樣融化加熱設備和外部保溫設施，共同製成凍土解凍時的強度弱化試驗儀。
