软土地区多种支护形式综合应用施工技术
|
摘要
温电厂四期工程位于软土地区,基坑工程中根据不同的深度和形式采用搅拌桩、钢板桩和砖砌体挡墙等多种支护开挖方式,并利用原有的基坑支护桩采取喷锚加固措施,实现了软土地基多种支护形式的综合利用。
Phase IV of Wenzhou Power Plant Project is located in a soft soil area,multiple supporting forms were adopted during excavation,such as mixing pile,steel sheet pile and masonry retaining wall,etc.,according to different depths and forms of foundation pit.Existing piles in the foundation pit were reinforced through spraying and anchorage,to successfully realize general utilization of multiple supporting forms on soft soil ground.
