The invention discloses a life-cycle treatment method of water inrush in a tunnel. The method comprises the steps that three-dimensional morphologic features of a water conductive structure of a water inrush zone in the tunnel are obtained by combining geological data, excavation data, detection results of comprehensive geophysical detection and numerical calculation results; grouting sealing water inrush is taken into account, surrounding rock physical mechanical parameters are improved simultaneously, design of a treatment scheme is conducted on the water inrush zone in the tunnel, and design of a keyhole and a drainage keyhole is conducted according to a water inrush main controlling structure; the stability of the tunnel in the construction period and the safety in the operation period are guaranteed by conducting numerical simulation on the tunnel section which is reinforced according to the design scheme; grouting construction is conducted according to the design scheme, a monitoring device is buried during the construction process, and feedback optimal design is implemented; inspection is conducted on the treatment effect of the grouting reinforcement section in the tunnel, and the excavation time is determined. According to the life-cycle treatment method of the water inrush in the tunnel, it is guaranteed that the surrounding rock in the tunnel construction period is stale and water inrush of the tunnel does not occur in the operation period, the chronic problem that nine of the ten tunnels leak is completely eradicated, and the effective treatment of the water inrush in the tunnel and the environmental protection are achieved.

The invention discloses a mud shale stabilizer. The mud shale stabilizer is acquired through the reaction of a silane coupling agent modified nanosilicon dioxide and a dendritic polymer. The inventionfurther provides a preparation method of the mud shale stabilizer. The mud shale stabilizer is prepared through the method. The hardness and softness combined physical blocking is realized with the help of the rigid blocking of the nanosilicon dioxide and the deformation filling of the nanoscale dendritic polymer, moreover, the strong absorption between a large quantity of end groups and the surface of the mud shale inhibits the hydration and swelling of the mud shale to achieve efficient chemical inhibition. The mud shale stabilizer achieves the double functions of the nanoscale physical blocking and the chemical inhibition, a new way and method is provided for the stabilizing the mud shale, and the mud shale stabilizer is of great theoretical significance and has an important application value.
