摘　　要：为进一步明确淤泥质土固结变形机理,本文以实际工程中所获取的淤泥质土为研究对象,通过试验研究的方式分析其淤泥质土在常规荷载、连续荷载及加载-卸荷条件等不同加载方式下的荷载-变形规律。研究结果表明,在一维荷载的作用下,由于淤泥质土初始含水量较高,固结压力施加初期排水过程相对较为缓慢;当到达一定压力后,土颗粒在荷载作用下开始重新排列。随后,结合不同荷载施加方式,进一步分析了淤泥质土在不同荷载条件下的响应特性。本文研究内容对提高淤泥质土条件下工程建设质量与安全性具有重要的现实意义。In order to further clarify the deformation mechanism of silty soil consolidation,this paper takes the silty soil obtained in the actual project as the research object,and analyses the loading-deformation law of silty soil under different loading methods such as conventional loading,continuous loading and loading-unloading con-ditions by means of experimental research.The results show that under one-dimensional loading,due to the high initial water content of silty soil,the drainage process is relatively slow in the early stage of consolidation pres-sure application;When a certain pressure is reached,the soil particles start to rearrange under the action of loading.Subsequently,the response characteristics of silty soil under different loading conditions were further analysed in combination with different loading methods.This study is of great practical significance to improve the quality and safety of engineering construction under silty soil conditions.
