深圳市丹平快速路一期工程勘察经验探讨

摘要

For finding out the geological condition of Danping expressway phase Ⅰengineering ,adopted various ex-ploration methods such as geological survey ,engineering drilling ,intersection plan,geophysical prospecting ,in-situ test, pumping(pump-in,water injection test,pore water pressure observation ,seismic safety evaluation,the physical and me-chanical properties tests of rock ( soil &water ) ,point load test of rock ,obtained the reliable first-hand original data ,sug-gestions on the report is reasonable and feasible ,and provided advantageous technical support and guarantee for the suc-cessful construction of the engineering .Combining with the engineering example ,analyzing the key techniques and diffi-culties of highway investigation including roads ,bridges,tunnels,culverts ,slope etc.The successful experience of this highway investigation is summarized ,which can be used for reference on similar highway Investigation project .%为了查明丹平快速路一期工程沿线的地质情况，勘察中采用地质调查、钻探、坑探、工程物探，多种原位测试方法、抽（压、注）水试验、孔隙水压力观测、地震安全性评价及室内岩、土、水的物理力学性质试验、室外岩石点荷载试验等综合勘察方法，取得了真实可靠的第一手原始资料。分析了包含道路、边坡、桥梁、隧道、涵洞等多种类型公路勘察的关键技术和难点，总结了此次公路勘察的成功经验，对类似公路勘察工程实施有一定的参考意义。
