一、概述大型火电厂的贮灰场,往往采用分期筑坝方式,即先修建一个较低的初期坝,然后在坝前贮灰,待其中水份通过排渗系统滤走后,再在沉积的灰面上加筑各级子坝,继续放灰到新的高程,沉积的灰体最终成了灰坝的主体(见图1),而这类灰坝稳定与否,很大程度上取决于它的浸润线的位置和形状。 First, an overview Large-scale thermal power plant ash yard, often by phased damming method, that is, to build a lower initial dam, and then storage of ash in front of the dam, pending the removal of water through the drainage system, and then deposited Of the gray surface plus sub-dams at all levels, continue to put the ash to a new elevation, the deposition of the gray body eventually became the main body of the dam (see Figure 1), and such ash dam stability, largely depends on The location and shape of the wetting line on it.
