海陆交界处取水口深基坑支护施工分析

取水口作为LNG码头用于汽化加工的主要结构设施，在整个LNG码头的建设中占据极为重要的地位。由于取水口需联通海域与陆域，且结构所处水位较深，在建设过程中不可避免地需进行深基坑支护与开挖。较通常的深基坑支护而言，波浪及海流对取水口基坑支护的不利影响不容忽视。文章就如何安全、有效地对海陆交界处取水口深基坑进行支护加固进行分析，可供类似工程借鉴。

Construction analysis of deep foundation pit supporting at the water intake in sea land border

The water intake which is the important structure facilities of vaporizing liquefied natural gas in LNG terminal is very important in the construction of LNG terminal. The construction process must be taken by supporting and digging for deep foundation pit, because the water intake must connect the sea area and land area and its top of pile of composite foundation is in the deep water. Compare with the traditional deep foundation pit supporting, the influence of wave force and current force cannot be ignored. This paper discusses on how to choose the right way of construction to support the deep foundation pit safely and efficiently at the water intake in sea land border, which can provide references for similar projects.
