深圳西部港航道工程勘探成功经验探讨

Successful experience of investigation in Shenzhen western port channel engineering

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。

For finding out the distribution range,the development degree and the causes of adverse geological phenomenon within the channel scope,evaluating the engineering geological conditions of the proposed site and judging the impact of the adverse geological phenomenon on channel construction,Shenzhen western port channel engineering investigation adopted various exploration methods such as geological survey,engineering mapping,geophysical prospecting（ shallow stratum profile）,engineering drilling and obtained the reliable first-hand original data. The suggestions in the investigation report are reasonable and feasible,which provide the advantageous technical support and guarantee for the successful construction of the channel. Combining with the engineering example, the key techniques and the difficulties of the investigation are analyzed, and the successful experience of the investigation is summarized,which can provide the reference for the similar investigation project.
