北江大堤石角堤段减压井试验分析

Experimental Analysis on Relief Wells in Shijiao Section of Beijiang Dike

简要介绍北江大堤石角堤段减压井的实际情况以及试验检测的内容,分析了本次减压井试验所取得的成果。试验结果分析表明,影响石角堤段减压井减压效果的主要因素是成井工艺和反滤方式而不是化学淤堵。因此,只要在成井工艺和反滤方式上加以改进和提高,在北江大堤石角堤段采用减压井进行减压防渗保护堤防是可行的。

Some actual statuses of the relief wells in Shijiao section of the Beijiang dike are presented and the experiment results are analysed. The results show that two primary factors affecting efficiency of wells are the welldrilling technology and inverted filter mode but not the chemical siltation. So it's feasible to protect the Beijiang dike by improving the two abovementioned factors.
