This paper presents a case study detailing the characteristics and mechanism of Shuiboxia landslide revival induced by the earthquake located in Bailongjiang River, 700 m upstream of the Shuiboxia Dam, in North West of China. After the“5.12”Wenchuan earthquake, landslide revived entirely and downstream zone cracked quite evidently. Based on the regional geology background, detailedly researched the deformation and mechanism of landslide. The research manifested that landslide revival is attributed to cumulative effect of seismic shaking resulting in reducing of strength parameters of the sliding zone, deformation were affected by the landform and evident amplification effect of landslide under the earthquake. Numerical simulation adequately explained the mechanism of landslide revival.

This study contributes to an in-depth examination of how Wenchuan earthquake disaster survivors utilize intensive built environment reconstruction outcomes (housing and infrastructural systems) to facilitate their long-term social and economic recovery and sustainable rural development. Post-disaster recovery administered via top-down disaster management systems usually consists of two phases: a short-term, government-led reconstruction (STGLR) of the built environment and a long-term, survivor-led recovery (LTSLR) of human and social settings. However, current studies have been inadequate in examining how rural disaster survivors have adapted to their new government-provided housing or how communities conducted their long-term recovery efforts. This qualitative case study invited sixty rural disaster survivors to examine their place-making activities utilizing government-delivered, urban-style residential communities to support their long-term recovery. This study discovered that rural residents’ recovery activities successfully perpetuated their original rural lives and rebuilt social connections and networks both individually and collectively. However, they were only able to manage their agriculture-based livelihood recovery temporarily. This research suggests that engaging rural inhabitants’ place-making expertise and providing opportunities to improve their housing and communities would advance the long-term grassroots recovery of lives and livelihoods, achieving sustainable development.

We take “5.12 Wenchuan earthquake” influence and one of the university in Mianyang urban area as the typical examples of the disaster preparedness community. We discuss how to plan the multiply disaster preparedness which in accordance to the geographical feature of hilly cities through the material properties of engineering materials research and study of the four-dimensional space disaster preparedness model.
