港口海岸岩土体渗流监测的荧光稀释模型研究
Study on mathematical model of the fluorescence agent dilution in seepage monitoring of rock and soil mass in port and coastal engineering
摘要
Abstract
To accurately and rapidly determine the seepage velocity of groundwater is of great practical signifi-cance for port and waterway engineering′s safety. According to the mathematical dilution model of solution concen-tration in logging, the seepage velocity of groundwater in rock and soil mass can be determined indirectly by the changes of the fluorescent dilution concentration. However, the traditional point dilution model does not take into ac-count that the vertical flow in the hole has an effect on the horizontal seepage flow velocity, which leads the model′s application to be limited. To overcome the influences of the vertical flow, the infinitesimal thought was utilized and generalized tracing dilution models were established from two aspects:Equality of Concentration and Conservation of Mass. Finally, the field test example of a breakwater project indicates that the generalized fluorescence dilution model based on Concentration and Conservation has better applicability, therefore, it can be used to solve the hori-zontal seepage velocity more accurately.关键词
