摘要
运用地质测绘、钻探、物探等方法,对同时涉及陆、海域隧道的沿海地区公路工程进行工可阶段勘察。通过分析勘察成果,陆域段主要影响隧道建设、运营安全的地质问题,主要为危岩、孤石、断裂构造;海域段问题,则主要为风化凹槽、断裂构造、孤石、液化砂土和软土震陷。对于这些问题,借鉴相似工程的经验,采用勘察中常用的类比法,提出针对某项目所涉地质问题的应对建议,对于该工程后续勘察设计阶段乃至建设期均具有指导意义。
Using geological survey,geophysical prospecting,drilling and other methods to explore tunnel and undersea tunnel in the stage of engineering feasibility study.Through the analysis of the survey results,some geological problems which affect the safety of construction or operation are found.For land area,the main problems are unstable rocks,boulders and faults,for sea area the main problems are alcoves,faults,boulders,sand liquefaction and seismic settlement evaluation of soft soil.For these problems,through analogy and drawing on the investigation of other similar projects,countermeasures for the problems are put forward,which also has certain guiding significance for the follow-up stages of these tunnels.
