摘要
Abstract
At present,pipe jacking technology is widely used in engineering construction in China,while it is seldom used in very long distance pipe jacking in hard rock in hydraulic engineering construction.Taking the hard rock pipe jacking construction of No.3 tunnel in Qianping Reservoir Irrigation Area as an example,the paper discusses the technical measures for very long distance pipe jacking in hard rock,such as the design of cutter head structure,modification of cutter structure and abrasion resistance,selection of pipe material,setting of pipe jacking device and relay,optimization of back slug control and thixotropic mud parameters,that promoted smooth construction of the project.关键词
