胶凝砂砾石坝穿坝建筑物布置与设计

Layout and design of dam-crossing structure of cemented sand and gravel dam

由于在我国已建成的胶凝砂砾石坝为数不多,高地震烈度区穿坝建筑物布置与设计研究相对较少,且穿坝建筑物位于坝体下部,存在静水压力大、空间狭窄、施工不便的难点,因此本文从穿坝廊道静、动力分析,导流管及供水管结构布置等方面入手,提出了胶凝砂砾石坝的穿坝建筑物设计和施工要点,对胶凝砂砾石坝的推广使用具有重要意义。

Due to the limited number of cemented sand and gravel dams that have been constructed in China and relatively few studies on the layout and design of dam-crossing structures in high seismic intensity areas,this paper addresses the challenges posed by dam-crossing structures located in the lower part of the dam,where they experience high static water pressure,limited space,and construction difficulties.Starting from the static and dynamic analysis of dam-crossing corridors,as well as the layout of diversion pipes and supply pipes,the paper presents the key design and construction considerations for dam-crossing structures in cemented sand and gravel dams.This research is of significant importance for the widespread adoption of cemented sand and gravel dams.
