软基处理深度快速计算的分析与探讨

本文结合上万高速公路软土地基的特征,将软基处理计算简化为软弱下卧层验算,采用Excel工作表进行编程,经简化计算获得最为经济的换填深度,避免了浪费,大大降低工程造价。文章最后提出可同时采用地基处理与基础尺寸变更两项措施来确保承载力满足要求,寻求施工最简化、造价最低化以及质量最可靠是未来软基处理的方向。

Combined with the characteristics of soft soil foundation of tens of thousands of highways, this paper simplified the calculation of soft ground treatment to the check calculation of weak underlying strata, adopted the Excel worksheet for programming, obtained the most economical replacement depth through simplified calculation, avoided waste and greatly reduced the project cost. In the end, the paper proposes that two measures can be adopted simultaneously to ensure that the bearing capacity meets the requirements, and that the direction of soft foundation treatment in the future is to seek the simplest construction, the lowest cost and the most reliable quality.
