在我国的山陝甘高原及其临近地区广泛分布着具有大孔隙结构的、遇水沉陷(湿陷)的黄土与黄土状土。在工农业大跃进的今天,在这些地区里将有更多的水工结构物、工厂、房屋等建筑起来,因此工程地质工作也将是非常繁重的。过去,我们在黄土与黄土状土分布地区进行工程地质工作时,主要系用挖探井的方法来采取黄土的原状试样的,这是一项既费力又不安全的操作方法,不能适应今日之需,因此必须要在这方面来个改革。
In China’s Shan-Shan-Gan plateau and its adjacent areas, there are widely distributed loess and loess-like soils with large pore structures and water subsidence (collapse). Today, in the Great Leap Forward of Industry and Agriculture, there will be more hydraulic structures, factories, houses and other buildings in these areas, so the engineering geology work will also be very onerous. In the past, when we carried out engineering geology work in areas where loess and loess soil were distributed, we used the method of digging wells to take the original sample of loess. This is a laborious and unsafe operation method that cannot adapt to today’s conditions. Needs, so a reform must be made in this area.
