根据近年来济南地区的工程勘察实践经验，对济南火成岩体的风化规律、风化带的划分标准等进行了初步的探讨与研究，从岩土工程角度对各风化带的工程特性进行了阐述，并对以往勘察评价中存在的若干问题进行了剖析，作出了有益的改进尝试。
According to the practical experience of engineering survey in Jinan area in recent years, the weathering rules of Jinan igneous rocks and the division standard of weathered zone are discussed and discussed. The engineering characteristics of each weathered zone are described from the perspective of geotechnical engineering. This paper analyzes some problems existing in the past survey and appraisal and makes some beneficial attempts to improve.
