摘要
结合工程概况,介绍了孔位布置情况及工程地质特征,通过对磊口大桥地层结构的分析,指出在丘陵、台地等地质条件复杂地区进行地质勘察,应对每个墩台位进行定点钻探,并提高取芯率,以确保地质资料的准确性。
Combined with practical work and based upon analysis of the strata of Leikou Bridge the arrangement and site selection of boring holes and engineering geological features are introduced.Author points out geological exploration in hill,platform and other regions with complicated geological conditions drilling should be made in every bridge pier.The core drilling ratio should be increase to ensure the accuracy of geological information.
