Abstract

The karst development degree in the factory area is extremely strong, the borehole dissolution rate is 67, the borehole line karst rate is 20.8 and the average buried depth of the karst cave is 27.59 m, which belongs to the deep karst. In both horizontal and vertical directions, the caverns are beaded, and the holes reveal an average of 3 to 4 caverns, and the roof thickness of the caverns is on average 1.04m.The roof is thin and broken, and the collapse of a single cavern will inevitably lead to the stability of the other caverns. In order to solve the problem of pile foundation stability, in the course of pile foundation construction, according to the height of the cave and the filling condition, according to the following principles:1) Schist, clay scheme treatment (H ≤ 2m) ;2) Low grade concrete treatment (2 m < H ≤ 4 m); 3) Hydrostatic chemical grouting scheme (4 m < H ≤ 10 m); 4) Casing follow-up wall protection scheme (H < 10 m).
