高烈度地震区浅埋大跨隧道施工技术及抗震材料

Construction technology and anti-seismic material for the tunnel at high seismic intensity zone

在高烈度地震区的软弱破碎岩体中修建浅埋大跨度隧道时,采取何种施工技术和选用什么样的抗震材料,才能满足抗震性方面的要求,这是工程界所关心的热点课题,文章以南昆铁路乐善村二号隧道为例,介绍了隧道的施工技术和选用的抗震材料,可为今后类似工程提供借鉴。

Leshancun No. 2 tunnel completed in 1997on Nankun railway, is situated in the weak and fractured rock mass. It is a kind of tunnel with shallow depth and large cross section in high seismic intensity zone. The paper introduces the successful experience about the construction technology and anti - seismic material taken in Leshancun No. 2 tunnel, which is a hot topic in engineering field and can also be taken as a reference for the construction of future projects.
