摘要
本文结合深基坑开挖课题进行了符合相似律的多土层土工模型试验研究。通过大量配方试验 ,得出了模型土的抗剪强度参数与各原料配比的变化规律 ;按 1∶2 0的几何比尺进行了多组多土层的深基坑开挖模拟试验 ,得出一些十分有用的结论。试验结果表明 。
A study of model tests for multilayer deep excavations that are accord with similitude law has been made in this paper.The regularity between shear strength parameters of model soils and the mix ratio of some materials are obtained after a large number of mix testing.The model retaining walls and bracing are prepared.Many sets of model tests of multilayer deep excavation in geometry proportion as 1∶20 are also performed,and some useful conclusions had been obtained.The results point that model test of excavation could be an economical and auxiliay method to study problem about excavation.
