The major causes for dyke breaches are the strong permeability of soil at the dyke breaches, resulting in infiltration or piping firstly, and nonuniform settlement on water side and land side of the dyke due to a long - term soakage of the dyke, further leading to cracking and erosion, and finally breaching of the dyke
潰口發生的主要原因是潰口處土壤組成透水性強，先發生散浸或管涌等險情，加上浸滄時間長，迎水面和背水面堤身沉陷不均勻，導致裂縫出現和沖刷的加劇也都促成潰口發生。 -
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。 -

本文結合商丘至開封高速公路底基層的修建，對大劑量水泥穩定粉質土材料組成配合比、強度、模量、抗裂性等變化規律進行了室內、外系統試驗研究。 -
Deep well dewatering of soft soil two - layer structure excavation is a kind of economical and effective dewatering method to ensure waterproof in deep excavation. nevertheless its negative impact on is often unavoidable. deep excavation dewatering often leads to the formation of a depressing cone, which may cause the cracking and even the breaking of surrounding buildings and utilities
在軟土地區二元結構地層，採用深井降低承壓水，是保證深基坑施工作業的一種經濟有效的方法，但也存在著一定的負面影響，因為降水勢必會形成降水漏斗，而引起基坑周邊地面沉降，可能導致周邊建築物和公共設施的開裂或損壞。
