西域砾岩灌浆过程质量控制模型研究与验证

Research and verification on quality control model of conglomerate grouting process in Western Regions

摘要

西域砾岩区域内帷幕灌浆是新疆地区水利水电工程防渗体系的重要组成部分，也是西域砾岩地区水利工程建设管理与质量控制的重点。通过对西域砾岩渗透特性以及常规灌浆施工质量控制方法的分析，综合考虑在设定浆液密度条件下，灌浆流量、灌浆压力与西域砾岩渗透特性参数的相关关系，通过定量分析建立了由Q、P、q和t构成的西域砾岩灌浆施工过程质量控制模型，并提出了新的灌浆质量控制参数，为西域砾岩地区水利工程灌浆施工提供了新的质量控制方法。提出的模型在莫莫克水利枢纽灌浆试验中进行了验证，实验证明了模型的适用性。

Abstract

Curtain grouting in the Xiyu conglomerate region is a critical component of seepage control systems for water conservancy and hydropower projects in Xinjiang. It is also a key focus for construction management and quality control in such projects within this geological context. Based on an analysis of the permeability characteristics of Xiyu conglomerate and conventional quality control method in grouting construction, this study systematically investigates the correlation among grouting flow rate, grouting pressure, and the permeability coefficient of Xiyu conglomerate under specified slurry density conditions. Through quantitative analysis, a quality control model for the grouting process, characterized by parameters Q(flow rate), P(pressure), q(permeability), and t(time), is established. Furthermore, new quality control parameters for grouting are proposed, offering an innovative approach for quality management in water conservancy projects within Xiyu conglomerate regions. The proposed model was validated through grouting experiments conducted at the Momoke Water Control Project, and the experimental result confirm its applicability and effectiveness.
