Model Test and Field Test of the Stability of Large Ultra-Deep Foundation

Abstract:

Based on the engineering background of Shijiazhuang six-line tunnel of Jing-shi Passenger Line, field measurements and indoor model test are both used to solve the stability issues of large ultra-deep foundation. Surface subsidence, pile displacement, and the force loss of prestressed anchors are analyzed. The results show that the model test and field test is basically the same, prestressed anchor cable can control surface subsidence and horizontal displacement of the pile effectively, so as to ensure the stability of the pit.
