一、前言 正在修建的沙岭子电站储灰场,采用水力除灰方法,分期筑坝,挡灰坝最终坝高41m。为了对灰坝坝坡进行稳定分析,需对粉煤灰的物理性及力学特性进行试验研究。由于该电站尚未建成出灰,故试验用灰均采用煤源与其相同、正在运行的下花园电厂灰库所沉积的粗细灰混排灰样,其化学成分见表1。

I. INTRODUCTION The Shalingzi Power Station ash storage area under construction uses hydraulic ash removal methods to build dams in phases. The final height of the dam is 41m. In order to analyze the stability of ash dam slopes, the physical and mechanical properties of fly ash should be studied experimentally. As the power station has not yet been built out of ash, the test ash uses the coarse and fine ash mixed ash samples deposited by the same ash as the coal source and is under operation at the Xiahuan Power Plant ash store. The chemical composition is shown in Table 1.
