风化岩体参数变化规律研究及工程意义

Study on Changing Rule of Weathering Rock Mass Parameters and Its Engineering Implication

岩体风化带划分的研究是工程地质勘察的重要内容。工民建、铁路、公路、桥梁、隧道等的设计与施工,不同风化带的各种参数是必要的基本数据。尤其是水利水电工程混凝土坝基建基面的确定,即风化岩体的利用,对于确保工程质量,减少开挖量及采取合理的工程措施具有重要的工程意义。

The study of zoning weathering rocks is an important matter of engineering geological prospecting. All sorts of parameters of different weathering rocks are essential basic data in the design and construction of industrial and civil buildings, railway, road, bridge and tunnel; especially the confirmation of foundation surface at concrete dam site in hydraulic and hydropower engineering, or the utilization of weathering rock masses,is of great importance to insure the engineering quality, reduce excavation volumes and take reasonable engineering measures.
