摘要：

近年来，国内在江河护岸工程实践过程中，创新优化出了预制混凝土铰链沉排护岸的新型结构形式，在多个护岸工程中得到成功应用并取得了良好的防洪护岸效果，但由于其水下排体尺寸较小，施工完成后水下部分的铺设情况很难被准确探测出来，也为水下部分的施工质量进行质量评定带来了困难。在对目前各种水下检测技术进行充分对比分析的基础上，提出超高分辨率多波束测深技术，并利用该技术成功地应用于长江武汉段铰链沉排护岸工程的水下部分施工铺设情况的勘测。实践证明该技术在定量检测预制混凝土铰链沉排工程水下铺设质量方面具有较大的优势，并可作为类似工程水下部分质量检测的技术手段。

Abstract:

The precast concrete slab connected with hinges is a new structure of embankment protection, and has been successfully applied to some embankment protection projects. However, since the size of underwater slab is very small, the underwater layout of concrete slab is difficulty to be detected, which brings about difficulty to the appraisal of underwater construction quality. Through analyzing and comparing various underwater inspection techniques, we present the multi-beam echo sounding with ultra high resolution which is applied to the investigation of embankment protection with hinge-connected concrete slabs in Wuhan segment of Yangtze River. This technique is proved to be advantageous in the inspection of underwater precast concrete slabs connected with hinges, and could also be applied to similar underwater engineering.

Key words: precast concrete slab connected with hinges, multi-beam echo sounding, quality, inspection
