【摘要】：公路工程具有投资规模大、建设周期长、占用资源多、影响因素复杂等特点,其工程地质勘察具有一定的程序和阶段性。结合作者多年的工程实践经验及规范编制对各阶段地质工作的深度、内容及方法进行了探讨,得出结论如下:(1)一条公路从规划到建成通车,一般需历经可行性研究、工程设计和施工建设等阶段,各阶段工作的目的和任务不同,对地质资料有不同的要求;(2)从了解→初步查明→基本查明→查明,每个阶段都具有不同的勘察深度,对应的它们勘察内容和方法也有差异;(3)工程地质勘察应按公路工程基本建设程序分阶段并按各阶段要求的深度开展工作,结合各阶段设计对地质资料的要求,统筹考虑现场地形地质条件的复杂程度、工程结构的特点和重要性、各种勘察方法的适用性和有效性,合理确定勘察方案及工作量,查明和正确反映场地工程地质条件,为工程设计提供资料完整、评价正确的勘察报告。该问题的研究对后期公路建设具有一定的指导意义。
[Abstract]:Highway engineering has the characteristics of large scale of investment, long construction period, taking up more resources and complex influencing factors, etc. Its engineering geological survey has certain procedures and stages. The depth, content and method of geological work in various stages are discussed in combination with the author's engineering practice experience and standard compilation for many years. The conclusions are as follows: (1) from planning to opening to traffic, a highway generally needs to go through feasibility study. In the stages of engineering design and construction, the objectives and tasks of each stage of the work are different, and there are different requirements for geological data; (2) from the perspective of understanding and preliminary identification, the basic identification and identification, each stage has a different depth of exploration, The corresponding survey contents and methods are also different; (3) the engineering geological survey should be carried out according to the basic construction procedure of highway engineering in stages and in accordance with the depth required in each stage, and combined with the requirements of geological data for each stage design, Considering the complexity of the topographic and geological conditions, the characteristics and importance of the engineering structure, the applicability and effectiveness of various survey methods, the rational determination of the investigation scheme and workload, and the identification and correct reflection of the site engineering geological conditions, Provide complete data for engineering design and evaluate correct survey report. The research of this problem has certain guiding significance to the later period highway construction.
