锚注加固能通过注浆和锚杆联合作用，快速提高加固体的抗渗强度和承载力，被广泛用于隧道、矿山巷道的加固工程。理论分析了锚注技术用于山区水闸加固工程的可行性，并以湖南某大型山区水闸除险加固工程为例，采用COMSOL软件，对传统注浆加固和锚注加固后山区水闸渗流场、位移场进行了对比分析，结果表明锚注加固能较好地提高基础抗渗能力，最大渗透压力减小35%，最小渗透压力减小60%；锚注加固能较好的提高基础承载力，最大竖向位移减小55%，最小竖向位移减小45%。锚注加固山区水闸闸底板完全可行，且较大地节省了成本，提高了工效，可在山区水闸加固工程中推广应用。

Bolt grouting technology can be used to improve the impermeability and bearing capacity of solid，which is widely used in the tunnel and mine roadway reinforcement． In this paper，a theoretical analysis is made of the bolting and grouting technology for mountain sluice reinforcement project feasibility． A large mountain sluices reinforcement project in Hunan is used as an example． By using COMSOL software，the traditional grouting and bolting reinforcement in sluice seepage field and displacement field are analyzed． The results show that the improved grouting can improve impermeability，maximum seepage pressure has decreased by 35%，the minimum osmotic pressure has decreased by 60%． Grouting can improve the bearing capacity of foundation，the maximum vertical the displacement has decreased by 55%，the minimum vertical displacement has decreased by 45%． It is feasible to reinforce the mountain gate by bolting and grouting，and it can save costs and improve work efficiency．
