重力式护堤石驳结构(图1)施工简便而被广泛采用。但在施工时受河道水位影响,石驳基础埋深一般都较浅,尤其是每年枯水位不同,历年所建埋深不一,以致在枯水季节,有的地段基础裸露,经波浪冲蚀,地基淘空,极易倾覆,影响石驳使用寿命。打一道板桩(图2)。这样做有如下优点:(1)由于板桩的防护作用,石驳基础埋深相对可以浅一点;(2)即使在枯水季节也不会使石驳基础裸露在外,导致基础底部淘空;(3)施
Gravity embankment stone structure (Figure 1) construction is simple and widely used. However, due to the influence of river water level during construction, the foundation depth of the stone barge is generally shallow. In particular, the dry water level varies from year to year. Due to the uneven depth of burial ground built during the dry season, , The foundation emptying, easily capsized, affecting stone bar life. Hit a sheet pile (Figure 2). This has the following advantages: (1) Due to the protective effect of sheet piles, the base depth of the stone barge can be relatively shallow; (2) the base of the stone barge will not be exposed even in the dry season; (3) Shi
