一种预压地基处理方案在建造变电站中的应用

Application of a Preloading Ground Treatment Method in the Construction of Substations

文章介绍了一种改进的预压地基处理方案:低位高真空分层预压击密法,介绍了其原理及工艺流程,举例了该方法的成功案例,并将该方法在某深厚软土地区的变电站中进行了应用分析,经计算分析验证了该方法处理后场地的工后沉降满足使用要求,且软弱土性质得到改善,最后提出可在变电站建造工程中推广使用的建议。

This paper introduces an improved preloading ground treatment method:the low-level and high-vacuum stratified preloading and compaction method.It introduces its principle and process flow,provides successful case studies of this method,and analyzes its application in a substation located in a deep soft soil area.Calculation analysis confirms that the post-treatment settlement of the site meets usage requirements and the properties of the weak soil are improved.Finally,it suggests widespread application of this method in substation construction projects.
