杭州市过境公路祥符桥至留下段,位于广义的长江三角州的南部边缘,途经地段沉积着厚度较大的第四系松散堆积物,主要是上更新统和全新统地层,其岩性特征:上更新统有冲积相砂卵层和冲湖相粘性土;全新统主要为海相软土(淤泥质土);河口区表现为砂性土。全线大部分路段存在以淤泥质亚粘土为主的软土层。我院在接到设计任务后,除进行详细的勘测钻探和试验外,还进行了现场十字板剪切试验和静力触探试验,为设计提供了较为真实的计算参数。
The Hangzhou-Hangzhou transit highway, Xiangfuqiao, remains until the southern margin of the Yangtze River Delta in the broad sense. Through the site, thicker Quaternary sediments are deposited, mainly the Upper Pleistocene and Holocene strata, and its lithological characteristics: Upper Pleistocene has alluvial facies sand and oolitic cohesive soil; Holocene is mainly marine soft soil (silt soil); estuary area is sandy soil. In most of the sections of the whole country, there is a soft soil layer mainly consisting of silt and clay. After receiving the design task, our hospital carried out on-site cross-plate shear test and static cone penetration test in addition to carrying out detailed exploration drilling and testing, which provided more realistic calculation parameters for the design.
