如果岩石经受不同程度的风化作用而降低了其力学强度,不仅给工程勘察与评价带来难度,且在某 种程度上影响了勘察成果在工程设计中的合理利用。为加深对风化岩的认识,促进风化岩划分标志的统一,提高工 程勘察质量,对风化岩组的形成、分带、风化类型及其组合做了概要讨论,并对工程勘察要点提出了建设性意见,旨 在供岩基工程地质勘察时参考和应用,也为工程设计提供宏观决策依据。 If the rock is subjected to different degrees of weathering and its mechanical strength is reduced, it not only brings difficulty to engineering survey and evaluation, but also affects the reasonable utilization of survey results in engineering design to a certain extent. In order to deepen the understanding of weathered rocks, promote the unification of the marks of weathered rocks and improve the quality of engineering investigation, the formation, zoning, weathering types and their combination of weathered rock groups are briefly discussed, and the main points of construction investigation are put forward. The opinions are intended to be used for reference and application of geotechnical geological survey of rocky foundation and also provide macroscopic decision-making basis for engineering design.
