深圳市丹平快速路一期工程勘察经验探讨

Discussion of Shenzhen Danping Expressway Phase ⅠEngineering Investigation Experience

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。

For finding out the geological condition of Danping expressway phase Ⅰ engineering,adopted various exploration 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 mechanical properties tests of rock（ soil water）,point load test of rock,obtained the reliable first- hand original data,suggestions on the report is reasonable and feasible,and provided advantageous technical support and guarantee for the successful construction of the engineering. Combining with the engineering example,analyzing the key techniques and difficulties 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.
