为查明航道范围内不良地质现象的分布范围、发育程度、形成原因,对拟建场地的工程地质条件做出评价,并判断不良地质现象对航道工程建设施工的影响。深圳西部港航道工程勘察采用地质调查、工程测量、工程物探(浅地层剖面)、工程钻探等多种综合勘探方法,取得了真实可靠的第一手资料,勘察报告中的建议合理可行,为航道工程的顺利建设提供了有力的技术支撑和保障。本文结合工程实例,分析了本次勘察工作的关键技术和难点,总结了勘察的成功经验,对类似海域及滩涂填海区勘察工程实施有一定的参考意义。
In order to find out the distribution range, development degree and formation reason of unfavorable geological phenomenon in the waterway, the article evaluates the engineering geological conditions of the proposed site and judges the influence of the adverse geological phenomenon on the waterway construction. The investigation of waterway engineering in the western port of Shenzhen adopts various comprehensive exploration methods such as geological survey, engineering survey, engineering geophysical prospecting (shallow stratum section) and engineering drilling, and has obtained first-hand and reliable data. The suggestions in the survey report are reasonable and feasible, The smooth construction of the project provided a strong technical support and protection. Based on the engineering examples, this paper analyzes the key technologies and difficulties of the survey and summarizes the successful experience of the survey. It is of some reference significance to the survey of similar sea areas and beach reclamation areas.
