基于湿陷性黄土强夯地基的变电站工程地基注水增湿方法研究
Research on Water Injection and Humidification methods for Substation Project Foundations Based on Dynamic Compaction of Collapsible Loess
摘要
Abstract
Dynamic compaction mechod is the primary method to address the collapsibility of loess,and water injection for moisture enhancement is a decisive factor in ensuring the quality of dynamic compaction.However,in practical engineering applications,water injection for moisture enhancement often faces significant challenges,such as uneven diffusion in"dual-layer structure"soil and insufficient moisture levels to meet the requirements of dynamic compaction.This paper investigates the diffusion patterns of water injection in"dual-layer structure"soils,employing two different methods of water injection for moisture enhancement.It compares the relationship between actual moisture content,deformation modulus,and settlement after compaction before and after moisture enhancement.The results show that the proposed graded and layered humidification method demonstrates a highly significant effect in addressing the moisture enhancement challenges associated with dynamic compaction in"dual-layer structure"soils.关键词
