摘要
从工程地质角度分析了堤防渗漏的原因 ,阐述了应用同位素示踪和天然示踪技术探测堤防渗漏的原理和方法 ,综合分析了北江大堤石角段 7+140~ 7+4 30渗流场特征 ,认为红层基岩中溶蚀现象的广泛发育使基岩的渗透性大大提高 ,而具集水功能的透水断层是历年洪水时发生喷水冒砂的直接原因。
Paper analyses the seepage field in Shijiao 7+140~7+430 dike of Beijiang by application of the techniques of isotopic tracer and natural tracer, points out that there are some central seepage roads in the rock, and that is why the piping often occure in blood.
