摘要
以我国西南某高速公路软弱地基上的高填方路堤开裂失效病害实例作为研究对象,以病害现象反复发生反复处治、病害认识不断加深的历程作为基础:先是因为对软弱地基处理方式失当而在路堤填筑过程中产生了侧向滑移病害;后又因为对病害机制认识不准确,导致制定的治理方案处治病害不彻底,使得路堤重新填筑过程中再次产生了侧向滑移病害;然后,再次因为对病害机制的认识还是不到位,并且对治理方案作用机理的理解不透彻,导致了病害进一步加重而致使路堤不得不重新填筑。通过对病害发生、发展过程的再认识和再评估,对病害发生机制进行了较为深入的探究和论述,对未能达到预期的病害处治对策进行了总结和反省,提出了病害防治的应对策略和思路,形成了病害处治方案且经历了实践的验证。
In this paper,a high fill emban km ent on weak ground cracking and lateral sliding was taking instance as the research object in southwest expressway,and as the base what the sliding disease development realized it＇s prevention and treatment process would be form.First,because of the inoperative treatment to weak ground,lateral sliding had occurred in the process of emban km ent filling.Then,the sliding disease prevention and treatment on the basis of the understanding of the disease mechanism was not complete,and so,in the process of emban km ent fill the lateral sliding diseases had occurred again.Even more,because of the deviation once again for the understanding of disease mechanisms after the second disease occurring,also the working mechanism of treatment measures was not grasped rightly,further it had leaded to the disease aggravated and the emban km ent would have to be filling once again.Based on the situation above,it was necessary to re-recognize and reevaluate the sliding disease occurred process and mechanism in this article,and summed up the failure reason for the sliding disease prevention and treatment,then it had be carried out for a summary and reflection,and put forward a coping strategies also a efficient treatment measure scheme.
