项目摘要
Underground openings are regularly made in rocks for mining, for tunnels to convey vehicles or fluids, for power plants near dams, for storage of wastes, and a variety of other purposes. Analyses used to determine the types of supports needed to prevent caving, begin with a specification of the original state of stress in the rock. Unfortunately, the horizontal stresses in rock cannot be determined analytically and no generally useful technique exists for economical measurement of these stresses. This project will involve an attempt to use a combination of a hydraulic fracturing technique with recently developed thin-film piezoelectric trans- ducers to determine the stress state. The goal of the project is to develop the technique so it can be widely used and to demonstrate its economic feasibility.
地下洞口通常是在岩石上开凿的,用于采矿、用于运输车辆或流体的隧道、用于大坝附近的发电厂、用于储存废物和各种其他目的。用来确定防止崩落所需的支撑物类型的分析,首先说明岩石中的原始应力状态。不幸的是,岩石中的水平应力不能以解析的方式确定,也没有普遍实用的技术来经济地测量这些应力。该项目将尝试使用水力压裂技术与最近开发的薄膜压电传感器相结合来确定应力状态。该项目的目标是开发这项技术,使其能够广泛应用,并证明其经济可行性。
