摘要
三峡工程永久船闸系在花岗岩山体中开挖而成，开挖的岩石边坡即为闸室的侧壁（用薄层钢筋混凝土衬砌）。为了切实有效地对边坡进行锚固以确保永久船闸的安全，随着施工的进行，在现场进行了边坡系统锚杆的动态设计。这里介绍动态设计的有关情况，内容包括：原边坡锚固支护设计，施工地质勘测成果，安全监测成果（边坡岩体松动范围，边坡锚杆应力大小），边坡系统锚杆动态优化设计和一期系统锚杆动态优化设计的效果（局部稳定可以保证，工程量明显减少）。
The permanent shiplocks of TGP are constructed by excavating the granite rock mass.The excavated steep slopes are the side walls of the shiplock chambers(lined by thin reinforced concrete).In order to guarantee the safety of shiplocks,the design method in situ is applied for the anchorage system.This paper introduces some related aspects of the design,including anchorage support design of the slopes,results of geologic investigation in the course of construction,achievements of safety monitoring(the loosened range of the slope rock,stresses of anchor rods in the slopes),optimization design of the system anchor rods and its effectiveness for Stage I system anchor rods(with local stability guaranteed and construction quantity decreased).
