“…However, although a number of geotechnical studies on issues caused by freezing and thawing and frost heaving have been conducted (e.g., Xu et al 2011;Zhang and Hulsey 2015), in particular, analytical and in situ experimental approaches that investigated the instability of slopes by freezing and thawing are limited (e.g., Harries and Lewkowicz 2000;Yu et al 2016;Zwissler et al 2016;Flynn et al 2016). Among this research, for example, Xu et al (2011) investigated the effects of frozen soils on seismic site responses in Anchorage, Alaska.…”
