Abstract:

The favorable engineering geological conditions and the structural integrity of rock mass make the Heidong ancient man-made underground caverns in Tiantai County, Zhejiang Province a large scale subterraneous quarry ever since the Sui Dynasty. Consisting of 21 single caverns, the group caverns situated in Xieshan cover an area of 24 000 m2, and the long axis of the caverns tend towards the same direction of the strike of the major two sets of geological structural planes. The lithology of the overall quarrying area is composed of the Upper Cretaceous Tangshang Formation layer No.6 off-white vitric ignimbrite. The value of the rock mass quality index Q is 53(class I). If the concept of modern underground caverns'architectural design is held, the maximum allowable span for the caverns'secular stability should not be greater than 50 m, and the maximum span of cavern No.5 actually reaches 81 m-promises to be perhaps the greatest span of single cavern. The several geological exploratory holes excavated by the ancients in the foot of Xieshan and the large angle-small section-high bench passing technique adopted in regional fault fracture zone effectively ensure the safety and secular stability of unsupported mining in unfavorable geological bodies. By piling massive quarrying waste in the cavern, the stability of the side walls is enhanced to some extent, and besides, the disposal method is also beneficial to the environment.

Key words: Heidong, large scale ancient quarry, gouge, rock mass quality, long term stability
