软土地基的桥梁隧道施工技术探讨

Inquiry on construction technology of bridge tunnel with soft-soil foundation

桥梁隧道施工规模、数量随着我国建筑行业、国民经济的发展而不断提升,国家、社会对桥梁隧道施工质量的要求也越来越高。着眼于施工难度较高的软土地基,探究了软土地基的含义与特点,通过分析软土地基桥梁隧道施工易产生的病害,从施工准备、施工预处理与加固处理三方面分析了桥梁隧道施工技术。

The bridge tunnel construction scale and quantity are gradually growing with domestic construction industry and national economy development,furthermore,the national and social demand for bridge tunnel construction quality is higher and higher too. Based on soft-soil foundation with high construction difficulty,the paper explores the definition and features of soft-soil foundation. Through analyzing construction diseases easily occurring for bridge tunnel with soft-soil foundation,it analyzes bridge-tunnel construction technologies from three aspects of construction preparation,construction preprocessing and reinforcement.
