摘要
以往中小型水库地质勘察工作主要采用钻探和人工探井,方法单一,很难对坝基岩体问题做出较为准确的判断。蒙自市蚂蚱冲水库通过声波试验配合传统勘察方法迅速而准确地对地基岩体风化界线和岩溶发育范围做出判断,提高了工程勘察的可靠度。
Drilling and artificial exploratory well were mainly adopted in medium and small reservoir geological survey work in the past. The method is single, which is difficult to accurately judge dam foundation rock problems. Ground foundation rock weathering boundaries and karst development scope are judged rapidly and accurately through acoustic test and traditional survey method in Mazhachong Reservoir, thereby improving project survey.
