为设计合理的BAGQ工程湿陷性土基础处理方案,以BAGQ工程陶瓷厂矩形槽段湿陷性土基础为例进行分析。首先根据工程地质条件及施工特点设计4种方案,之后通过比较4种方案的投资、施工和安全可靠性及当地认可程度三方面,选择出了合适方案。研究结果表明最优方案为方案4,即采用防渗+排水+适应变形措施的基础处理方法,工程自2015年运行至今状况良好。该湿陷性土基础处理方法打破了传统的湿陷性土基础常规处理方法,可为同类湿陷性土基础处理提供借鉴。
In order to design a reasonable foundation treatment scheme for collapsible soil of BAGQ project, a case study of collapsible soil foundation in rectangular groove section of BAGQ Engineering Ceramics Factory was taken as an example. First of all, according to the engineering geological conditions and construction characteristics of the design of four kinds of programs, then by comparing the four kinds of programs investment, construction and safety and reliability of the local recognition of three aspects, select the appropriate program. The results show that the optimal scheme is scheme 4, that is, the basic treatment method using seepage prevention + drainage + adaptive deformation measures, and the project has been in good condition since its operation in 2015. The collapsible foundation treatment method breaks the traditional method of conventional collapsible foundation treatment and provides reference for the same kind of collapsible foundation treatment.
