过去,我们总认为黄土塬地区地表激发条件差、干扰历害,要想得到好的同相轴反射波,就必须采用一套复杂的野外工作方法,因此我们对黄土塬区搞反射法有畏难情绪。人的正确思想,只能从社会实践中来。一九七四年我队在批林批孔运动的推动下,在陕西澄郃黄土塬地区,大胆开展了反射法的试验工作,取得了较好记录,对黄土塬区的地震勘探有了初步认识,现介绍如下。 In the past, we always thought that the conditions of surface excitation in the Loess Plateau were poor and the disturbance was harmful. In order to obtain good in-phase reflection, we must adopt a complex set of field work methods. Therefore, we are afraid of the reflection in the Loess Plateau. The correct thinking of man can only come from social practice. In 1974, thanks to the campaign of “Picking up Borets and Punch holes”, our team bravely carried out the test of reflection method in Chenghuang loess plateau area of ​​Shaanxi Province and obtained good records and preliminary preliminary exploration of the seismic exploration in loess plateau area Understanding, are described below.
