摘要
岩溶地区地质条件复杂,地基处理不当会造成安全问题或施工困难、造价提高等不良后果。以某框架-剪力墙结构为例,分析了场地局部存在上覆土层较厚的土洞、岩溶裂隙破碎带,且土洞及岩溶裂隙破碎带周边存在软～可塑粉质黏土层的地基处理技术及考虑多种因素共同作用下的基础沉降。通过设置后浇带,不均匀沉降得到较好控制。
Under the complex geological conditions of karst area,improper foundation treatment can cause safety problem or construction difficulty,cost increase and other adverse consequences.Taking a frame-shear wall structure as an example,this paper analyzes foundation treatment technology and foundation settlement under the combined action of soil hole in local thick overlying soil layer site,karst fissure broken belt,and the soil hole and karst fissure broken belt surrounding exist soft-plastic silty clay layers.By setting later poured belts,the uneven settlement is perfectly controlled.
