摘要
超前管棚支护是隧道施工中穿越软弱破碎围岩的一种有效的预支护方法。介绍超前管棚的受力原理与模型、设计与施工要点及适用范围等,并结合工程实例,论证超前管棚技术在隧道施工中的应用价值。
The shed-pipe advanced support that passes through soft cracked rock mass in tunnel construction is an effective pre-supporting method. This paper introduces the applicative field and technical features of shed-pipe advanced support construction technique used in tunnel construction under unfavorable geological conditions, analyzes its force behavior and characteristic of construction method. Then the advantages and prospect of this technique are studied with engineering examples.
