摘要
本文论述了在淤泥质土的超大超深基坑中运用特殊断头的钢栈桥进行深基坑土方开挖，在土方开挖时在栈桥末端进行土方放坡，从栈桥底部绕越后下至基坑底的技术，缩短了钢栈桥的长度，节约了施工成本。
This paper discussed the use of special steel trestle breakage in the super large and deep foundation pit of mucky soil in deep foundation excavation. In excavation, the techno-logy used around from the bot om of the trestle down to the pit bot om to slop the earthwork at the end of the trestle, shorten the length of the steel trestle, saving the construction cost.
