摘要
结合淮盐高速公路软基先导段真空联合堆载预压法处理地基的设计、监测方案实例,根据现场监测资料和效果检验数据对真空预压加固效果进行了分析和评价,历时32个月现场试验结果表明:真空预压加固效果良好,地基软土各项指标得到明显改善,地基有效应力增长,地基强度增加,地基稳定性得到提高。
Combining with design and testing scheme practice of soft foundation precursor segment vacuum joining load precompression method to deal with foundation, analyzes and evaluates vacuum precompression consolidating effect according to local testing datas and effective testing datas, experimental result of lasting a period of thirty-two months makes clear that vacuum precompression consolidating effect is fine, all of foundation soft land targets acquire improvement obviously, foundation effective stress is prolonged and its intensity is increased, foundation stability acquires improved.
