近年来日本为了合理利用建筑材料而研发了梯形胶凝砂砾石(CSG)坝,该类坝还能有助于改进设计,提高施工效率。它可以将坝址附近不适合于用作混凝土骨料的风化岩石料及其他材料利用起来,而且其材料开采加工方法和设备简单。由于原料开挖区和施工设备区的大小可以受到限制,所以此类水坝可以看成是环境友好型坝。介绍了梯形胶凝砂砾石坝的主要特点。
In recent years, Japan has developed trapezoidal grit gravel (CSG) dams to rationalize the use of building materials. Such dams can also help improve design and construction efficiency. It can be used near the dam site is not suitable for use as aggregate concrete weathered rock materials and other materials to use up, and its material processing methods and equipment is simple. Since the size of raw material excavation area and construction equipment area can be limited, such dams can be considered as environment-friendly dams. Described the main features of trapezoidal pergamous gravel dams.
