Field Trip #2: Co-seismic landslides and Major Engineering Projects Site Selection

Chengdu---Luding---Moxi---Chengdu

Situated on the eastern periphery of the Qinghai-Tibet Plateau, Luding County emerges as a preeminent locale nestled within the expanse of the western Sichuan highlands and plateaus. Distinct in its profound trench-like formations, it stands as the epitome of entrenched gorge regions in this terrain. This geographical canvas, adorned with its uniqueness, unfolds within a realm of seismic dynamism, posing formidable challenges to infrastructure conception and realization. Nevertheless, it also stands as an unparalleled crucible for the examination of geohazards and their far-reaching engineering ramifications.

Embarking upon a comprehensive two-day expedition, participants will have the privilege of acquainting themselves with remarkable feats of engineering ingenuity. Among these, the Yakang Bridge and Luding Hydropower Station stand as a testament to human innovation harmonizing with the environment's demands. Notably, the historic Luding Chain Bridge, a scarlet emblem of tourist allure, unveils an ancient iron link to the past. Moreover, the excursion promises insights into the cataclysmic traces left by bygone seismic events, with the Wuzhisuo and Mogangliang landslides marking the landscape as enduring witnesses. Enthroned amidst this captivating backdrop is a venerable township, its foundations rooted in the embrace of glacial water deposits. This illustrious settlement presents a living connection to history, poised gracefully upon the remnants of glacial epochs. Such a symphony of marvels awaits an expedition that unearths both the awe-inspiring legacies of our predecessors and the intricate dialogue between humanity and nature's most formidable facets.

Field Trip #3：The Three Gorges Hydropower Project and Reservoir Landslide Disasters

Chengdu---Badong---Three Gorges Dam---Chengdu

The Three Gorges Hydropower Station is the world's largest hydropower station and the largest construction project in China. The accompanied issues, such as immigration, relocation, and environmental issues, have attracted widespread attention from the moment of its establishment. After the impoundment of the hydroelectric reservoir, the hydrological environment of the original bank slope has been greatly changed, leading to the revival of many large landslides. This scenic route focuses on the Three Gorges hydropower project and reservoir landslide disasters, passing through Badong County and Yichang City in Hubei Province. The activity will last for two days. The two key scenic spot in this route are: (1) Badong Field Comprehensive Experimental Station: it was established in the Huangtupo landslide with the largest volume in the Three Gorges Reservoir Area. A three-dimensional comprehensive observation is carried out for this landslide. It allows for close observation of the geological structure and deformation characteristics of the landslide. (2) Three Gorges Dam: You can come to the vicinity of the top of the Three Gorges Dam to view the whole scenic area. Understand the construction process and functions of the Three Gorges Dam by visiting different scenic spots.

Field Trip #4: Xi'an Ground Fissure and Loess Landslide (Cancelled)

Chengdu---Xi’an

Xi'an, which was known as Chang'an in ancient times, has a history of more than 3,100 years and was set as a capital city 1,100 years ago. It is the old capital of 13 dynasties and the birthplace of the first emperor (Qin Shihuang) in China and is also one of the important birthplaces of Chinese civilization and the Chinese nation. During the two-day visit, you will be shown the urban geological hazards and historical sites in Shaanxi Province. We have selected the most typical ground fissures, located in Yuhuazhai, Qingliangshan Park and Xiying Road, and you will introduce the features of ground fissures on the first day. After that, we will bring you to the Xi’an City Wall, which was built in the Ming Dynasty in 1370 and has more than 600 years of history. On the second day, you will visit Jingyang County on the Chinese Loess Plateau, where loess landslides often occur (e.g., Dabaozi landslide, Jiangliu landslide, Dongfeng landslide and Shutangwang landslide). You will observe the unique features of loess strata. Then, you will visit Lishan landslide in Lintong District. After the site tour, you will visit the eighth wonder of the world-Terracotta Warriors of the First Chinese Emperor, which is the largest on-site museum in China.
