Numerical analysis on wave generated by the Qianjiangping landslide in Three Gorges Reservoir, China

Phreatic line calculation and stability analysis of slopes under the combined effect of reservoir water level fluctuations and rainfall

“…The monitored underground water level at J1 was unchanged, which is similar to the results from the the simplified method leading edge of the landslide, which is about 6 km from the estuary and about 1.5 km from Qianjiangping landslide on the left bank of the the river (Chen et al 2003;Yin et al 2012;Sun et al 2016aSun et al 2016bXiao et al 2010aXiao et al 2010bYin et al 2015;Wang et al 2016). The geographical location is shown in Fig.…”

“…Therefore, rainfall and reservoir water level fluctuations are the main driving factors for the recurrence of the ancient D r a f t landslides in the Three Gorges Reservoir area. Especially after the impoundment of the Three Gorges Reservoir, the occurrence of Qianjiangping landslide on July 13, 2003, in which 14 people were dead and 10 were missing, urged people to think about this important issue (Wang et al 2004(Wang et al 2008Yin et al 2015;Xiao et al 2010aXiao et al 2010bYin et al 2015;Wang et al 2016).…”

The Maximum Height and Attenuation of Impulse Waves Generated by Subaerial Landslides

“…This equation yields the upper limit of the surge amplitude and provides a theoretical means to predict the near-field maximum water surface elevation. Yin et al [18] employed a fluid-solid coupling model based on a general moving object collision model and the renormalization of the group turbulent model. Bosa and Petti [19] established one-dimensional and two-dimensional models for landslide surges based on the nonlinear shallow water model.…”

A Simplified Solution for Calculating the Phreatic Line and Slope Stability during a Sudden Drawdown of the Reservoir Water Level

“…For example, the landslide that occurred on 13 July 2003 at Qiangjiangping on the Three Gorges Reservoir claimed many lives and was responsible for considerable infrastructure losses. The accident serves as a profound warning [2,3] and strongly motivates further study of this type of natural disaster. Many studies have confirmed that changing water levels are the main cause of landslide events [2][3][4][5][6][7][8][9].…”
