摘要
在湖泊相沉积的深厚淤泥土场地开挖深基坑,由于坑底卸荷隆起导致基坑边坡位移、失稳是一个常见的技术难题。本文提出了采用粉喷桩多孔板暗撑加固抗隆起技术,与边坡喷锚网、钢管桩联合支护结构相结合。实践证明,取得了安全、经济的效果。
In the deep foundation pit of lacustrine thick silt exist many slope displacement and unstability. The authors suggested porous plate at the pit bottom, together with slope anchorage net and steel pipe piles to strengthen the foundation. Practice proves that the new method is safe and economic.
