一、引言浅坑注水试验是水文地质工程地质勘测过程不可缺少的一种试验。这种方法对测定岩层的渗透系数不但经济,而试验的结果也可以满足我们设计上的要求。为此,采用这种方法在目前来讲还是很普遍的。浅坑注水仪在过去几种类型中存在最大的缺点,是不能把真实的渗透情况记录下来,只是根据几个点连一条理想的曲线,这样常常给试验结果带来一定的误差。更不能通过这条曲线看出渗透的其实规律。另一方面在人力的消耗上也是很浪费的。
I. INTRODUCTION Shallow pit water injection test is an indispensable test for hydrogeological engineering geological survey. This method is not only economical for determining the permeability coefficient of rock formation, but also the result of the experiment can meet our design requirements. For this reason, using this method is still very common at present. Shallow pit water injection device in the past, there are several types of the biggest shortcomings that can not be the real record of the infiltration, but according to a few points with an ideal curve, which often give some error in the test results. Can not see through this curve actually penetrate the law. On the other hand, it is also a waste of manpower.
