| 摘 要： | 北部湾大道位于灰岩分布区,灰岩为石炭系天子岭组,岩溶发育,表层被第四系冲积层覆盖,岩土稳定性较差。通过分析工程沿线地质环境条件,采用层次分析和模糊综合评判方法（AHP-FUZZY）对岩溶地面塌陷进行综合评判,并依据评判结果进行岩溶地面塌陷发育强弱分区,进而对未来岩溶塌陷发展趋势作出预测与评价。

| Abstract: | Northern Gulf Boulevard is in the area with carboniferous limestone of Tianziling group, karst development, surface covered by Quaternary alluvium and poor geotechnical stability. In this paper, the geological environment conditions along the project are analyzed and analytic hierarchy as well as Fuzzy Comprehensive Evaluation Method is used to comprehensively evaluate karst ground subsidence. Based on the results of evaluation zonings are made by development extent of karst ground subsidence and predictions are made for their future development trend. |
