摘要
述及室内土工试验的目的及其质量对基本建设的重要性 ,列举了若干次土工试验质量问题造成工程事故的实例 ,指出在质量检查中发现的各项试验的质量问题 ,最后提出了提高土工试验质量的关键及应采取的措施徐变对混凝土坝的应力、应变影响较大 ,文章针对沙牌碾压混凝土拱坝埋有正、倒垂线及一定数量应力应变计的特点 ,提出一种反演沙牌坝体碾压混凝土徐变度的方法 ,并研制了相应的计算程序。
This paper describes the purpose of laboratory soil test and the importance of its guality to construction. Several examples concerning the injury caused by the accident of structure due to the erroneous result of soil tests are illustrated. The erros of testing result of different tests discovered by investigation are pointed out in this paper and the key to improve the guality and the methods are suggested.
