Abstract

Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on depth to intact bedrock and groundwater conditions – often on dangerous or still-failing slopes. Horizontal-to-vertical spectral ratio is a low-impact technique capable of rapidly providing key information on the subsurface. Here we develop a robust workflow for constrained minimization of horizontal-to-vertical spectral ratio data and develop constrained horizontal-to-vertical spectral ratio profiling methodologies. We present results from a number of landslide sites in eastern Australia and demonstrate the utility of horizontal-to-vertical spectral ratio in delineating both fractured-rock aquifers at high-risk sites and colluvium–bedrock contact on active landslide sites, where traditional seismic methods were not practical.

利用受限水平-垂直谱比反演技术修复斜坡坍塌
与气候变化相关的降水模式增加可能会加剧斜坡崩塌率。此类事件对受影响的当地社区造成极大破坏。快速工程修复解决方案通常需要立即进行现场特征描述,包括完整基岩深度和地下水状况的信息--通常是在危险或仍在崩塌的斜坡上。水平-垂直光谱比是一种影响较小的技术,能够快速提供地下的关键信息。在此,我们开发了一套强大的工作流程,用于约束性地最小化水平-垂直光谱比数据,并开发了约束性水平-垂直光谱比剖面方法。我们展示了澳大利亚东部一些滑坡地点的研究结果,并证明了水平-垂直谱比在划定高风险地点的断裂岩石含水层和活动滑坡地点的冲积层-岩石接触面方面的实用性,在这些地点,传统的地震方法并不实用。

期刊介绍: Geophysical Prospecting publishes the best in primary research on the science of geophysics as it applies to the exploration, evaluation and extraction of earth resources. Drawing heavily on contributions from researchers in the oil and mineral exploration industries, the journal has a very practical slant. Although the journal provides a valuable forum for communication among workers in these fields, it is also ideally suited to researchers in academic geophysics.
