摘要
针对珠江三角洲隧洞工作井基坑深度较大,场地空间狭窄及强透水、地层软弱及传统施工技术难以解决当前问题等突出问题,文章以珠江三角洲隧洞为背景,通过对地质条件的分析和评价,优化了水下灌注桩施工技术,提出了地下连续墙、成槽施工等多种施工工艺相结合的技术方案进行基坑围护,结果表明该项技术在复杂场地条件下深基坑施工中具有良好的效果.
Abstract
In response to prominent issues such as the significant depth of foundation pits,limited site space,high permeability,weak ground layers,and the inadequacy of traditional construction techniques,focusing on tunnels in the Pearl River Delta,by analyzing and evaluating the geological conditions,this paper optimizes the construction technology for underwater jet grouting piles and proposes a technical solution that combines various construction methods such as underground diaphragm walls and trenching.The results demonstrate that this technology is highly effective for deep foundation pit construction in complex site conditions.
