岩体风化的综合分带研究

岩体的风化不仅会引起岩石物质成份、化学成份变化 ,而且也引起岩体裂隙、岩体完整性的改变。因而风化岩体中裂隙数量、岩体块度的变化与岩体的风化程度具有较好的对应关系。论文研究了用岩体裂隙间距、岩体的完整性指标、岩石质量指标对岩体风化程度进行分带 ,较好地将岩体风化分带与岩体结构、岩体工程特性紧密地结合起来。在岩体风化程度的定量划分上作了新的探索。

STUDY ON INTEGRATED ZONING OF WEATHERING DEGREE OF ROCKMASS

Weathering agency can result not only in vaviation of physical components and chemical components of rock, but also in change of joints and integrality of rock mass in the weathering process. Therefore, a better correlation exists between amounts of joints and block size in rockmass and degree of weathering. In this paper, the weathering zones are distinguished in accordance with joint spacing, integrality index of rock mass and rock quality index and in combination with rock mass structure and its engineering properties. A quantitative classification of weathering zones is carried out and good results are also obtained in the paper.
