[0002] The tunneling process often causes the redistribution of surrounding rock stress and the change of groundwater level in the stratum. The change of groundwater will directly affect the soil structure and the balance of soil stress. The vibration waves generated by underground blasting will also have different degrees of impact on the stability of surrounding rock and the safety of surface buildings. All these influences will inevitably cause soil deformation, which is intuitively manifested as sinking and cracking of the surface and buildings, displacement of tunnel surrounding rock and support, etc. Whether these changes will endanger the safety of buildings and affect the normal life order of the city must rely on effective construction disaster prevention monitoring.
