Research on failure state and mechanism of shear key of segmental joint in immersed tunnel

Hu Zhinan;Xie Yongli;Lai Hongpeng;Yan Changgen;College of Highway,Chang'an University;  
In order to research failure states and mechanisms of shear keys of segmental joints in immersed tunnel of the Hong Kong-Zhuhai-Macao Bridge,the three dimensional numerical simulation by ANSYS software was adopted to simulate working conditions of bending and twisting of immersed tunnel segments caused by longitudinal and transverse uneven foundation settlements as well as uneven back-filling loading. At the same time,large-scale immersed tunnel segmental model tests with scale ratio of 1∶ 4. 69 was carried out on three immersed tunnel segments based on a subgrade settlement experimental platform of Chang'an University. Comparing shearing force results of shear keys from numerical models and tests,it can be seen that vertical shear keys play main role under bending and twisting working conditions. Shearing status of shear keys under bending working condition is bending and shearing,while shearing lag effect exists in twisting working condition. Furthermore, failure mechanisms of shear keys were obtained through analyzing vector diagrams, failure characteristics and failure process of vertical shear keys. Based on this,structural optimizing measures on shear key design were put forward.
