一、本工程砂层能否做持力层 从深水码头基槽开挖纵断面(见图2)上可以看到长度标尺300～950米处,基岩面上的复盖层以砂层为主。“工程地质勘察报告”对该砂层作了如下的描述: “该砂层由粗砂细砂砾砂组成,呈灰白色金黄色等,粗砾砂的矿物成份以石英为主,
First, the project can be carried out by the sand layer holding depth from the Deepwater Pier Foundation Longitudinal excavation (see Figure 2) can be seen on the length of the ruler 300 ~ 950 meters, the bedrock surface cover to the sand layer is the Lord. The Geological Prospecting Report describes the sand as follows: "The sand is composed of coarse sand and fine gravel sand and has a grayish-yellow color. The mineral content of the gravel sand is mainly quartz,
