Monitoring Design and Instrument Embedment of Pandaoling Tunnel During Consolidation Period;

Through two field-participated practical engineering,this paper separately introduces the embedding technologies of test tube in single drilling,in bored cast-in-situ pile and in artificial digging pile,in order to correct the error caused by improper embedment of test tube and offer a reference for similar engineering in the future.

In consideration of the limitation of related criteria and practice of previous projects,especially the limited endurance of instruments to high hydraulic pressure,some technical and managing experience in embedment of interior instruments of pumped storage power stations is analyzed theoretically and practically.
