罗田水库提标改造工程坝基帷幕灌浆设计

Luotian Reservoir upgrading and renovation project dam foundation curtain grouting design

摘要

罗田水库作为珠三角水资源配置工程的重要节点，其安全运行对保障区域供水安全和防洪体系至关重要。随着时间的推移和功能标准的提升，水库大坝面临坝基岩土透水性偏大等问题，导致渗漏现象严重。为了提升大坝的安全性和稳定性，提出了一套系统的坝基帷幕灌浆设计方案，以罗田水库为例，详细介绍了罗田水库的工程概况、存在的问题、渗漏量估算及分析、帷幕灌浆设计、施工技术要求及常见问题的处理。设计的坝基帷幕灌浆方案实施后，罗田水库大坝渗漏得到明显改善，效果显著，达到防渗加固的目的。验证了坝基帷幕灌浆方案的有效性和可行性，提出的设计方案为类似病险水库大坝的防渗加固工程提供参考和借鉴。

Abstract

As an important node in the Pearl River Delta water resource allocation project, the safe operation of Luotian Reservoir is crucial for ensuring regional water supply safety and flood control system. With the passage of time and the improvement of functional standards, reservoir dams are facing problems such as high permeability of rock and soil in the dam foundation, leading to serious leakage. In order to improve the safety and stability of the dam, a systematic design scheme for dam foundation curtain grouting was proposed. Taking Luotian Reservoir as an example, the engineering overview, existing problems, leakage estimation and analysis, curtain grouting design, construction technical requirements, and common problem handling of Luotian Reservoir are introduced in detail. After the implementation of the designed dam foundation curtain grouting scheme, the leakage of the Luotian Reservoir dam was significantly improved, and the effect was significant, achieving the goal of anti-seepage reinforcement. The effectiveness and feasibility of the dam foundation curtain grouting scheme were verified. The proposed design scheme provides reference and inspiration for anti-seepage reinforcement engineering of similar dangerous reservoir dams.
