隧道施工对黄土松动区内力和位移影响研究
Research on effect of tunnel construction on internal force and deformation at loosed loess area
摘要
Abstract
In order to have a profound understand of the internal force and deformation rules in loose areas of the loess tunnel caused by the construction process of tunnel, some axial force meter of bolts, single-point displacement transducer and embedded earth pressure cells were embedded into the loose areas during the Tian-Ding freeway tunnel construction, which lie in the Dingxi city of Gansu Province, China. Based on the measured data, combining with the on-the-spot construction state, the internal force and surrounding rock displacement change rules at loosed loess area are analyzed and summarized. According to these rules, the later construction of the tunnel have carried some corresponding adjust and achieved satisfactory result. The results also have an important guidance for the design and construction of similar loess tunnel.关键词
