Abstract
This paper takes the soil tunnel of a long-distance water transmission channel project as the research background,in which the operation life of the tunnel continues to increase,the soil tunnel keeps running at full load for a long time,and there may be leakage,cracks,erosion pits,insufficient strength of concrete components and excessive deformation inside,which will affect the normal operation of the whole channel.Through the field investigation,the artificial investigation and detection of hidden dangers inside the tunnel,cracks,leakage,erosion pits and other defects and problems in different degrees inside the tun-nel were found.According to the classification of defect problems,three different construction methods,technological processes and repair materials were used to carry out professional repair of the three types of defects found inside the tunnel,and the effect evaluation was carried out.Finally,good results were a-chieved.At the same time,advanced technologies such as surface wave method,ground penetrating radar and three-dimensional laser scanning technology are further introduced and adopted to clarify the"reces-sive"defects existing in the tunnel and establish a tunnel safety monitoring system,so as to provide a sci-entific basis for the treatment of internal defects in the tunnel at the later stage.It has certain guiding sig-nificance to the engineering management of a long distance water transmission channel engineering manage-ment department.关键词
