钻孔注水试验,是水文地质及工程地质勘探中,最常采用的一种试验方法。水文地质勘探孔,如果地下水位埋藏较深,不能进行压风机抽水时,为了求得各岩层概略的滲透系数,就必须进行钻孔注水试验,至于工程地质勘探孔,注水试验的采用,就更为普遍。不过:以往所做试验方法,每次只能求得一个地段(或岩层)的滲透数据,这样逐段试验,对于勘探进度,颇有影响,为了解决这个问题,本文拟将多段注水试验的方法,提出来与同志们商讨。
Drilling water injection test, the hydrogeology and engineering geological exploration, the most commonly used test method. If the groundwater table is buried deeper than the groundwater level, and the compressor can not pump water, it is necessary to conduct the drilling water injection test in order to obtain the approximate permeability coefficient of each rock formation. As for the engineering geological exploration holes and the water injection test, For the universal. However, the test methods used in the past can only obtain the permeability data of one lot (or rock formation) at a time. In this way, the section-by-section test has an impact on the exploration progress. To solve this problem, , Put forward to discuss with comrades.
