| 中文摘要:城市化的发展，使市政道路改造工程越来越多，如何科学有效地利用拟建期的勘察资料，节约勘察成本，成为工程勘察关注的焦点。通过对场地地形地貌和地质构造、地层和水文地质条件、岩土物理力学性质、场地稳定性评价和地震效应、岩土工程重点分析评价等岩土工程要素进行分析，对比前后各要素，探讨勘察资料的时效性，进而确定勘察点布置和深度，以及取土（水）样和原位测试工作量。最后以具体工程为例，探讨勘察要点，指出利用拟建期的勘察资料应主要考虑4.0 m以内的地层变化，重点勘察路基破损的路段。 |

| Abstract:With the urbanization development, municipal road reconstruction project gets increasingly common and how to scientifically and effectively use the survey data in the planning period and save the cost become the focus of engineering survey. Based on the analysis on the geotechnical engineering elements of site topography and geological structure, stratum and hydrogeological conditions, rock and soil physical and mechanical properties, the stability evaluation and seismic effect and geotechnical engineering evaluation, by the comparison of the above key elements, the timeliness of the survey data is discussed to determine survey point arrangement, exploration depth and the work load of sampling and in-situ test. Take the specific project as an example, the paper discusses the key points of investigation, and points out that for survey data in planning period, the formation variation within the depth of 4.0m should be mainly considered and the focus should be on broken roads. |
