摘要
在软土地基上修建高等级公路 ,控制施工过程中路基的稳定及工后沉降是一个关键性的岩土工程问题 .为了弄清各种工程措施处理软土地基的效果及沉降变形规律 ,并指导工程的大规模施工 ,通常选取具有代表性的路段作为试验路段 .文中介绍了杭州绕城公路 (北段 ) K2 8+63 0～K2 8+73 0软基处理试验段的现场变形测试成果 ,并用有限元的数值分析结果与实际观测结果进行比较 .通过比较研究 ,一方面可以检验数值计算分析 ,使之更加完善 ,另一方面也有助于验证相关土工试验计算参数的准确性 .
Constructing highway on the soft clay ground is a key question of geotechnical engineering to control settlement after work and stability. In order to realize the effect and settlement regularity improved by various engineering measure, and to direct construction on a large scale,it is usually to select some representative route as experiment to research. This paper introduces deformation surveying result in Hangzhou outer circumferential highway in reach of k28+260~k28~730 experiment route, and to compare the finite element analysis with real scene deformation surveying result. On the one hand, to examine and correct numerical calculation, on the other hand, to contribute to the test calculation reference numbers related.
