摘要
Abstract
Taking the access section of Hejiang car depot of Line 18 of a Metro as an example,the safety evaluation of the shield tunnel adjacent inclined crossing the operating first-grade highway is carried out through numerical simulation and other methods,the deformation of the road surface is analyzed,and the corresponding countermeasures are put forward.The results show that the impact of the shield tunnel adjacent inclined crossing the first-grade highway is small,and the control values are within the allowable range of the code.There are some differences between the theoretical calculated value and the construction monitoring value.The main deformation control measures such as shield informationization construction and ground grouting reinforcement are put forward.关键词
