一种评价黄土及黄土地基湿陷敏感性的新方法
摘要:目前,工程界对黄土湿陷性的评价仅限于湿陷量的概念,没有涉及到湿陷敏感性的问题,对湿陷敏感性的评价尚处于探索阶段,很多学者对此做了研究和论述,并提出了多种评价方法,但尚未形成一致的意见,在工程中如何对湿陷敏感性进行定量判别也没形成统一的标准。根据大量的工程实践资料,在不增加试验工作量的前提下,分别提出了一种新的黄土湿陷敏感性及黄土地基湿陷敏感性的评价方法,并给出了相应的定量评价标准。方法简单可行,易于在工程中应用,经实践检验效果良好。虽如此,仍需在工程实践中得到进一步的完善和改进。
Abstract:The evaluation of loess collapsibility in engineering is confine to the concept of collapse settlement,and the evaluation of collapsible sensibility is not involved in previous research.The evaluation of collapsible sensibility is still at the exploratory stage.Although studies and discussions,as well as numerous evaluation methods have been presented by many scholars,thereis no consensus of opinion proposed,and no unified standard of quantitative evaluation on the collapsible sensibility provided.Based on a large number of engineering practice data,and on the premise of no increasing amount of tests,a new evaluation method of the loess collapsible sensibility and loess foundation collapsible sensibility is presented,and the corresponding quantitative evaluation standard is provided.The method is simple and feasible,and easy to beapplied in engineering.This method has been proved to be effective by practice.Even so,this method still needs to be further improved in engineering practice.
