岩溶地段桩基施工溶洞决策表法处理研究及应用

Research and Application of Decision Table Method in Pile Foundation Construction of Karst Area

结合广州某高速岩溶地段桥梁桩基施工遇到的溶洞处理问题,对整个场地的桩基溶洞勘察数据信息进行了分类统计分析,在经济适用的原则下,提出了不同溶洞、不同处理方式的决策表机制,达到了全面考虑、简化决策、及时处理的目的,同时可以对溶洞处理措施费用进行事前预算,加强了工程管理措施手段,取得了较好的实践效果。

Combined with the problem of karst cave treatment encountered in the construction of bridge pile foundation in a high-speed karst section of Guangzhou,the classification and statistical analysis of pile-based cavern survey data of the whole site was carried out,under the principle of economic application,the decision-making mechanism of different caves and different treatment methods is proposed,achieved the purpose of comprehensive consideration,simplified decision-making,and timely processing,at the same time,the cost of the cave treatment measures can be budgeted in advance,achieved good practical results.
