| 摘 要： | 在对厚度较薄的软基路段采用换土垫层法进行处理过程中,清淤厚度和换填层的厚度直接关系到路基沉降与路堤稳定性。文章以某高速公路多处软基病害路段处理效果检测为例,详细探讨了清淤厚度的电测深法无损检测技术。实践表明,采用电测深法检测技术,较传统钻探取芯方法可以更快速、更准确地查清清淤及换填层的厚度,为施工单位及业主的决策及时提供相关数据资料和科学依据。

| Abstract: | In section of soft foundation with embedding fleet,thickness thin for freeway,soil replacement and padding methods were always adopted. But during processing,thickness of cleanup silt and displacement related to sedimen- tation of roadbed,stabilization of road,which arose attention. In case of detection measurement to processing methods of many soft foundation of one freeway, electric sounding detection methods for thickness of soft foundation were discussed particularly. Practice shows that,compared with t... |
