| 摘 要： | 水闸闸基隐患严重威胁水闸安全，闸基淘空是水闸较常见的隐患之一。闸底地基垫层在水闸上下游水位差的作用下，经一段时间的运行后，往往会形成强渗流层和淘空区，洪水到来时便产生管涌，危及水闸的安全运行和人民的生命财产安全。利用探地雷达技术可探测出闸基冲刷剥蚀程度、淘空区的位置、范围、发育程度及规模，便于及早采取防范措施，进行加固处理。探地雷达技术是水闸闸基隐患探测的有效手段，雷达图像的特征分析是雷达资料解释的关键，通过雷达图像的特征分析，可判译出闸基隐患的具体部位和类型。

Feature analysis on radar pictures for detecting hidden danger of floodgate base |
| |
| Abstract: | Hidden danger is seriously threatened the security of floodgate and the safe of the life and property of the people. One of which is made hole of hollow in a base of floodgate where can be lead to piping in flood, as has been work for a time, the base layer is produced strong permeate area and hollow area under the high/low water level difference. It be detected the degree of scouring, denudation, the position of hollow area, growth level and scale by the GPR technique, so a control measure and properly reinforce there is adopted as early as possible, the GPR technique is a effective method of detecting hidden danger in a base of floodgate, the key to explain radar data is the feature analysis of radar picture. |
