摘要
针对某原支护结构设计为“灌注桩+搅拌桩止水+预应力锚索支护+喷混凝土”的深基坑支护超期后,提出两种基坑加固方案,并分别介绍两种方案的工艺流程、操作要点、优缺点、使用范围等内容。
In view of the expiration of a deep foundation pit supporting structure designed as“grouting pile+mixing pile+prestressed anchor cable support+shotcrete”,two reinforcement schemes for foundation pit are proposed,and the technological process,operation key points,advantages and disadvantages,and application scope of the two schemes are introduced respectively.
