BAGQ工程矩形槽段湿陷性土基础处理方法优化选择

Optimal Selection of Foundation Treatment Method of Rectangular Slot Collapsible Soil in BAGQ Engineering

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 treatment scheme for collapsible soil foundation of BAGQ project,this paper takes BAGQ project as a case object.First,according to the engineering geological conditions and construction characteristics,four schemes are designed.Then,by comparing the investment,construction,safety and reliability and the degree of local recognition,the suitable scheme is chosen from four schemes.The results show that the optimal scheme is the 4th scheme,that is,combination of seepage control with drainage and deformation is used to deal with the foundation.The project has been running well since 2015.The collapsible soil foundation treatment method breaks the traditional treatment method of collapsible soil foundation,which can provide reference for the similar collapsible soil foundation treatment.
