Rapid construction method for rockfill self-compacting concrete gravity dam
The invention relates to the technical field of water conservancy projects, and discloses a rock-fill self-compacting concrete gravity dam rapid construction method which comprises the following steps: S1, treating a bedrock surface and preparing a cleaning site, and pouring a concrete cushion layer after the bedrock surface is treated; s2, a formwork is installed; s3, screening and warehousing the rockfill; s4, producing and transporting the self-compacting concrete; s5, pouring of self-compacting concrete; s6, maintaining the self-compacting rock-fill concrete; and S7, checking the safety performance of the stepped gravity dam body through a numerical simulation method and a rigid body limit equilibrium method. According to the technical scheme, the risk of safe operation and the construction cost can be reduced, meanwhile, the construction efficiency is improved, and the construction period is shortened.
本发明涉及水利工程技术领域，公开了堆石自密实混凝土重力坝快速施工的方法，包括以下：S1，基岩面的处理及清洗场地的准备，基岩面处理完成后浇筑混泥土垫层；S2，模板的安装；S3，堆石的筛选及入仓；S4，自密实混凝土生产及运输；S5：自密实混凝土的浇筑；S6，自密实堆石混凝土的养护；S7，通过数值模拟法和刚体极限平衡法对阶梯式重力坝体的安全性能进行校核。本发明的技术方案能够降低安全作业的风险和施工成本，同时，提高了施工效率，缩短了施工周期。
