摘要
建筑岩基的岩体完整性划分是否准确直接影响到建筑物的安全性、施工的可行性及经济性，文章通过钻孔取芯观察岩石破裂面，研究岩质坚硬程度，结合辅助钻进速度、进尺、压力及返水情况，综合判断岩体的完整性，即不要进行统计又无需做测试，具有直观、快速、易行等特点，经２８个工程实例开挖检验吻合率达１００％，准确率高。
Whether the rock mass integrity determination of building's rock foundation is correct will directly affect its security, constructive feasibility and economic results. Through drill-hole's coring to observe the fracture plane of rocks, to study the hardness of rocks, combining with the conditions of auxiliary drilling rate, footage, pressure and backflow, the rock mass integrity is determined comprehensively. It neither needs statistics nor test, and is of visible, fast and easy-to-use characteristics. The identical rate reached 100% by the test of 28 engineerings' excavations.
