快速检测方法在大坝砾石土心墙填筑中的应用

Application of Rapid Testing Method in Placement of Gravel Soil Core of Dam

砾石土料填筑质量控制需要测定土料含水率和砾石(P5)含量,若采用常规方法则用时较长,介绍了一种新的砾石土填筑质量控制的快速检测方法。阐述了该方法的基本原理以及该方法在长河坝水电站大坝砾石土心墙填筑中的具体运用。该方法在砾石土填筑质量控制中具有广泛的应用前景。

Water content in soil material and gravel( P5) concentration should be tested in quality control of gravel soil placement. The conventional test method will last longer time. In this paper,a new rapid testing method for quality control of gravel soil placement is described. Firstly,the basic principles of the method is presented,then the application of this method in placement of gravel soil core of Changheba dam is described. Broad application prospect for quality control of gravel soil core placement is expected.
