摘要
该文介绍了在武汉长江隧道工程武昌明挖隧道的设计与施工中,根据复杂的地质条件和周边环境条件,借鉴武汉地区基坑工程的成功经验,深基坑设计采用了地下连续墙、钻孔灌注桩、SMW工法桩和拉森钢板桩等支护方式及坑周悬挂式竖向隔渗与坑内深井减压降水相结合的防水方式,阐述了在周边复杂情况下,深基坑施工的应对措施及施工过程中问题的处理,总结了施工控制的要点。
The article introduces the supporting methods of underground diaphragm,cast-in-situ pile, SMW processing pile and Lashen sheet pile used in the design of deep pit and the waterproof method combining the pit-surrounding overhead vertical seepage insulation with the in-pit deep-well pressure-relief water reduction by using the successful experience of the pit project in Wuhan area for reference and based on the complicated geological condition and the peripheral environmental condition in the design and construction of Wuchang Open Excavating Tunnel of Wuhan Changjiang River Tunnel Project,sets forth the countermeasures of the deep pit construction and the problem treatment in the course of construction under the complicated peripheral condition,and sums up the gist of the construction control.
