The invention discloses a treatment method for tunnel collapse and water burst, and relates to the technical field of tunnel engineering. The method comprises the following steps that drilling and sampling are conducted, specifically, drilling and sampling are conducted on a planned tunnel route through a drilling and sampling device, the sampling depth is 30-50 m, and when a tunnel is built to reach two thirds of the sampling depth, drilling and sampling are conducted. According to the arrangement of the treatment method, when collapse and water burst happen to the tunnel, adjacent non-collapse areas are reinforced and drained in the first time, the following steps can be carried out only when the height of the water level in the tunnel is lower than the set height, the collapse area is reinforced, the collapse area is repaired, and the collapse area is repaired. By means of the structure, when gravel and soil are cleaned, the possibility that outer-layer substances in a collapsed area go to the collapsed ar
