摘要:
在输水工程建设中,当避无可避不得不穿越活动断裂时,就需要进行抗错断设计。需要找准断裂带的最新活动部位,并研究其错断位移分布模式和位移量,才能确保抗错断措施的有效性。在滇中引水工程隧洞穿越的龙蟠—乔后断裂分带性特征研究成果的基础上,综合提出了断裂带最新活动部位的判定方法,探索性的提出了活动断裂变形带宽度计算方法以及蠕滑活动断裂位移量分布模型。研究成果为隧洞工程抗蠕滑错断设防措施的设计及设防部位的确定提供了依据。
Abstract:
During the construction of water conveyance project, when it is unavoidable to cross active faults, it is necessary to carry out anti-fault design. In order to ensure the effectiveness of anti-fault measures, it is essential to accurately identify the latest active segment of the fault zone and study its distribution mode and displacement. Based on the research results of the zoning characteristics of the Longpan-Qiaohou fault zone traversed by the tunnel of the central Yunnan Water diversion project, the paper comprehensively proposes the determination method of the latest active position of the fault zone, and innovatively puts forward the calculation method for the width of the active fault deformation zone and the displacement distribution model of the creeping active fault. The research results provide a basis for the design of anti-creep and anti-fault fortification measures and the determination of the fortification position of tunnel engineering.
