| 摘 要： | 在介绍管波勘探法的探测原理及其在阳阳高速公路应用情况的基础上,从经济、工期、风险等角度分析了管波勘探法与其它方法的优势。分析表明采用1桩1孔+管波勘探的方法进行岩溶桩基的勘察是可靠的,该方法比1桩2孔方法节省费用约36%,比1桩1孔+后处理桩底溶洞的方法节约16%,同时争取了至少1个月的工期。

| Abstract: | Based on the introduction of principle of tube wave detecting method and its application on Yangyang Expressway, comparative study between tube wave detecting method and other methods have been carried out in the fields of economy, construction period and risk. The results have shown that the tube wave detecting method is dependable, and its cost saving can reach at least 36% being compared with two - hole - drilling in one pile, and at least 16% while being compared with one - hole - drilling in one pile and pile bottom grouting, meanwhile, at least one month of construction period can be reduced. |
