摘　　要：针对软岩大硐室支护研究和工程实践少、支护困难的问题,工作人员提出了基于支护原理的软岩硐室联合支护原则,软岩硐室从增加围岩联合支护的角度,对大断面软岩硐室的刚度、支护范围和稳定性进行了扩展,加固后软岩大硐室的变形明显减小。实践证明,采用预应力锚杆、锚索和适时的二次注浆加固,可以较好地解决大断面软岩空间支护问题,可为同类工程提供一定的效益和借鉴。因此,本篇文章对于联合支护技术在软岩大硐室中的应用进行响应的分析,仅供参考。In response to the lack of research and engineering practice on the support of large soft rock caverns,and the difficulties in supporting them,the staff proposed the principle of combined support for soft rock caverns based on the support principle.From the perspective of increasing the combined support for surrounding rocks,the stiffness,support range,and stability of large cross-section soft rock caverns were expanded,and the deformation of the large soft rock caverns after reinforcement was significantly reduced.Practice has proven that using prestressed anchor rods,anchor cables,and timely secondary grouting reinforcement can better solve the problem of large cross-section soft rock spatial support,and can provide certain benefits and reference for similar projects.Therefore,this article provides a response analysis of the application of combined support technology in large soft rock caverns for reference only.
