大型矿山岩土工程深基坑支护方案优化研究

Study on Optimization of supporting scheme for deep foundation pit of geotechnical engineering in large mine

由于传统支护方案,在进行深基坑支护时对围护结构的计算不精准,因此支护稳定度低,无法实现对岩土工程深基坑的稳定支护.针对这一问题,进行大型矿山岩土工程深基坑支护方案优化研究.首先,设计深基坑支护结构细部,再通过计算围护结构,完成深基坑支护方案优化.设计实例分析,结果表明,优化的支护方案支护稳定度明显高于实验对照组,可以实现对深基坑的稳定支护.

Due to the traditional support scheme,the calculation of the retaining structure is not accurate when supporting the deep foundation pit,so the stability of the support is low,which can not achieve the stability of the deep foundation pit of geotechnical engineering.In view of this problem,the Optimization Research on the supporting scheme of deep foundation pit in large-scale mine geotechnical engineering is carried out.First of all,the supporting structure details of deep foundation pit are designed,and then the supporting scheme of deep foundation pit is optimized by calculating the retaining structure.The results show that the stability of the optimized support scheme is significantly higher than that of the experimental control group,which can achieve the stability of the deep foundation pit.
