摘要
应力释放法近年来被发展到混凝土实际应力量测研究中,国内研究人员通过对各种量测方法的试验与工程实际应用的研究,取得了一定的成果。将混凝土应力释放法归纳为5种,即剥层法、套孔法、钻孔法、盲孔法和开槽法,分析5种方法的基本原理,研究它们的发展现状和工程实践的可行性,总结各种方法的优点和不足,并提出需要进一步研究的问题和方向。
In recent years,stress release method is applied in the study of concrete actual stress measurement.Some results have obtained through the researches of test on various measurement methods and actual applications in the domestic.Five methods of concrete stress release are induced in this paper,namely stripping method,encasing hole method,drilling hole method,blind hole method,grooving method.Basic principles of five methods are analyzed,current situation and engineering practice feasibility are studied,the advantages and disadvantages of various methods are summarized,some problems and directions which need to be studied further are posed.
