The magnitude (Mw) 7.8 earthquake that struck North Canterbury on New Zealand’s South Island on the evening of 14 November 2016 caused widespread damage to infrastructure, in particular to road and rail within the South Kaikōura Transport Corridor (SKTC). This is the main transport corridor along the east coast of the South Island, and the coseismic landslides covered and destroyed parts of the State Highway 1 (SH1) road, as well as the railway lines. Post-earthquake aftershocks and significant rainfall events (e.g. Cyclones Debbie, Cook and Gita), further mobilised the de-stabilised greywacke rock mass and paleo-landslide debris that mantled the slopes. Indeed, the SKTC was affected by > 80 separate landslides that have impacted either the rail corridor, the road corridor, or both. A number of different landslide mechanisms occurred, including shallow translation slides of existing paleo-landslide debris and rotational slumping, as well as rock mass failure via wedge, planar or toppling. Here, we report on monitoring of three case study landslides, using multi-temporal analyses of digital elevation data (from LiDAR, TLS and UAV surveys), real-time extensometer and land deformation monitoring using GPS receivers, as well as survey prisms. These datasets provided important monitoring of near-surface movement, important for risk management along the transport corridor during the reinstatement works.

新西兰凯库拉南部运输走廊沿线滑坡的震后监测

2016 年 11 月 14 日晚发生在新西兰南岛北坎特伯雷的 7.8 级地震对基础设施造成了广泛破坏，尤其是南凯库拉运输走廊 (SKTC) 内的公路和铁路。这是南岛东海岸的主要交通走廊，同震滑坡覆盖并摧毁了部分国道 1 (SH1) 公路以及铁路线。地震后的余震和重大降雨事件（例如飓风黛比、库克和吉塔）进一步移动了覆盖斜坡的不稳定的灰岩岩体和古滑坡碎片。事实上，SKTC 受到了超过 80 个独立的滑坡的影响，这些滑坡影响了铁路走廊、公路走廊或两者。发生了许多不同的滑坡机制，包括现有古滑坡碎片的浅层平移滑坡和旋转坍塌，以及通过楔形、平面或倾倒造成的岩体破坏。在这里，我们报告了三个案例研究滑坡的监测，使用数字高程数据（来自 LiDAR、TLS 和 UAV 调查）的多时相分析、实时引伸计和使用 GPS 接收器的土地变形监测，以及测量棱镜。这些数据集提供了对近地表运动的重要监测，对于恢复工程期间运输走廊沿线的风险管理非常重要。TLS 和 UAV 测量）、使用 GPS 接收器的实时引伸计和土地变形监测，以及测量棱镜。这些数据集提供了对近地表运动的重要监测，对于恢复工程期间运输走廊沿线的风险管理非常重要。TLS 和 UAV 测量）、使用 GPS 接收器的实时引伸计和土地变形监测，以及测量棱镜。这些数据集提供了对近地表运动的重要监测，对于恢复工程期间运输走廊沿线的风险管理非常重要。
