摘要
在桂林岩溶区的岩土工程勘察中,地基稳定性评价应注意考虑溶洞或土洞的规模尺寸、形态、洞内充填物、地下水等因素的影响;石灰岩、粘性土、粉土的地基承载力应采用多种方法综合取值,要敢于打破经验方法的束缚;在地下水位变化较大的地方,应按分层总和法进行地基土的变形计算;岩溶地基处理,应注重新处理方法和新施工工艺的尝试和运用.
In the investigation of geotechnical engineering in Guilin karst region, the influence factors of scale, dimension, shape, filling, groundwater of cave and soil cave should be taken into account in the appraisal of ground stability. There are various methods for the determination of bearing capacity for limestone, cohesive soil and silty soil. When the groundwater lever changes much, the ＂layerwise summation method＂ can be used in the calculation of foundation settlement. In the process of karst ground treatment, new treatment methods and techniques can be applied.
