摘 要
随着城市基础设施建设的快速发展,地下连续墙作为一种高效、可靠的深基坑支护结构,在复杂地质条件下的应用日益广泛。然而,复杂地质环境对施工技术提出了更高要求,传统施工方法在适应性与经济性方面面临诸多挑战。本研究以典型复杂地质条件为背景,系统分析了地下连续墙施工过程中可能遇到的技术难题,并提出了一种基于地质特征优化的施工技术方案。通过数值模拟与现场试验相结合的方法,研究了不同地质条件下槽壁稳定性、泥浆配比优化及接头处理等关键技术问题。结果表明,优化后的施工技术显著提高了成槽效率和墙体质量,同时有效降低了施工风险和成本。本研究的创新点在于首次将地质参数与施工工艺参数进行耦合分析,建立了适用于复杂地质条件的施工参数预测模型,为类似工程提供了理论支持和技术参考,具有重要的工程实践价值。关键词:地下连续墙; 复杂地质条件; 施工技术优化; 槽壁稳定性; 泥浆配比
Abstract
With the rapid development of urban infrastructure construction, underground continuous walls (UCWs) have been increasingly applied as an efficient and reliable deep excavation support structure in complex geological conditions. However, such complex geological environments pose higher requirements on construction technology, and traditional construction methods face numerous challenges in terms of adaptability and cost-effectiveness. This study, based on typical complex geological conditions, systematically analyzes potential technical difficulties encountered during UCW construction and proposes an optimized construction technology scheme derived from geological characteristics. By integrating numerical simulations with field experiments, key technical issues such as trench wall stability, slurry proportion optimization, and joint treatment under different geological conditions were investigated. The results indicate that the optimized construction technology significantly enhances trenching efficiency and wall quality while effectively reducing construction risks and costs. The innovation of this research lies in the first-time coupling analysis of geological parameters with construction process parameters, establishing a predictive model for construction parameters applicable to complex geological conditions. This provides theoretical support and technical references for similar projects, demonstrating significant engineering practical value.Key words:Underground Continuous Wall; Complex Geological Conditions; Construction Technology Optimization; Slot Wall Stability; Slurry Proportion
