Abstract: This paper first introduces the important value of geotechnical engineering survey and design under complex geological conditions, and then lists some common survey technologies suitable for complex geological environment at this stage, including rock stratum drilling technology, in-situ test experiment, indoor test analysis and so on. Finally, the key points of compiling geotechnical investigation and design scheme are summarized, such as determining the spacing and depth of geotechnical investigation points. On this basis, the geotechnical investigation and design scheme based on complex geological conditions is compared with the traditional investigation and design scheme by means of comparative experiment. The experimental results show that the geotechnical engineering survey and design scheme proposed in this paper significantly improves the survey accuracy, meets the needs of survey and design, and provides favorable conditions for geotechnical engineering construction.

地質勘察作为岩土工程建设前期的一个基础环节,旨在获取工程施工范围及周边的地质、水文等信息,在此基础上开展工程设计,为后续的工程基础施工提供有价值的参考。在复杂地质条件下,为了保证勘察工作顺利开展,以及获得全面、精确的地质数据,必须要编制岩土工程勘察设计方案。调查发现,现阶段许多施工单位将主要精力放在工程设计与施工方面,而对于前期的地质勘察作业没有给予高度重视。在这一背景下探究适用于复杂地质环境的岩土工程勘察设计技巧,无论是在提高勘察效率,还是增强勘察数据精度方面均有积极帮助。
