Abstract
Based on the typical fault analysis of large diameter slurry shield of Beijing underground diameter, the corresponding treatment and preventive measures were proposed, these faults including cutter stuck, shield tail leakage, tail brush damage, segment erector failure, etc. Meanwhile, the shield was maintained in advance with predictability through the oil sample analysis, and the intact rate was guaranteed objectively. In the construction process, the "zero inventory" and a set of scientific equipment management methods like factory management were introduced, making the intact rate of shield machine grow from 60 % to 85 % and even higher, so the normal tunneling progress was ensured.
