  • Prehistoric Walled Settlements in the Chengdu Plain
    PREHISTORIC WALLED SETTLEMENTS IN THE CHENGDU PLAIN BY WANG YI 王毅 (Chengdu Municipal Institute of Cultural Relics and Archaeology) Translated by Wenbin Peng 彭文彬 and Mark Pittner Abstract The Baoduncun Culture, named after prehistoric walled settlements in the Chengdu Plain, was a regional archaeological culture distributed in the western part of the Sichuan Basin along the upper reaches of the Yangzi River and centered in the Chengdu Plain. Dating from the Late Neolithic (or Chalcolithic) and contemporaneous with the Long- shan cultures of northern China, its recent discovery constitutes a major achievement in the clarification of the pre-Qin archaeological sequences in southwestern China. The Baoduncun Culture, like the Sanxingdui Culture that followed it, is highly instructive demonstrating the special status that the Sichuan Basin, particularly its western por- tion, holds as a place of origin and a center of development of ancient civilization in the upper Yangzi River valley. History of Baoduncun Culture discoveries Major fieldwork relating to the Neolithic period in the Sichuan Basin began in 1953, when the Bianduishan 邊堆山 site was discovered in Mianyang 綿陽 County (now City), Sichuan Province, and provision- ally dated to the Neolithic period (Xi’nan Bowuyuan Choubeichu 1954: 11).1 In the autumn of 1963, Sichuan University and the Sichuan Provincial Commission of Cultural Relics Management undertook a joint excavation at the Yueliangwan 月亮灣 locus of the Sanxingdui 三星堆 site in Guanghan 廣漢 County (now City) (site locations are 1 The Editors thank Wenbin Peng and Mark Pitter for their draft translation of the paper presented here in revised form. The Editors have provided additional references, including those for a number of field results and preliminary excavation reports that have been published since the submission of the manuscript in Chinese.

  • Collapse and Landslide Hazard Characteristic Along Railway Line in Chengdu-Lanzhou of China
    Collapse and Landslide Hazard Characteristic along Railway Line in Chengdu-Lanzhou of China Dongliang He School of Civil Engineering, Hunan University of City, Yiyang, Hunan 413000, China e-mail: [email protected] ABSTRACT The Chengdu-Lanzhou Railway locates in the Sichuan province and Gansu province. After the “5.12” Wenchuan earthquakes, a massive landslide, collapse, debris flow occurred, worsening the geological environment. The collapse of the mountain behind the Mao County valley gully elementary school is one of these many serious hazards, threatening the life and property security of 160 teachers and students in the school, as well as the residents around. In order to find out the form, structural morphology, scale, deformation behavior and the formation mechanism of the collapse hazard, studies on the structure forms, buried depth and the engineering construction, engineering geology emergency exploration to the collapse hazard has been carried out in this paper. Through varied reconnaissance means, such as geodesy, exploration and field testing, the causes, form, scale, scope, steady state and perniciousness of the collapse and the landslide next to the teaching building have been ascertained, and the deformation mechanism has been analyzed to provide a reference to the further assessment of prevention and control engineering, ensuring the successful construction of the Chengdu-Lanzhou Railway. KEYWORDS: landslide; collapse; Wenchuan earthquakes; assessment INTRODUCTION The Chengdu-Lanzhou Railway locates in the Sichuan province and Gansu province. It starts at Chengdu, going via Guanghan, Shifang, Mianzhu, Mao County, Songfan before arriving at Jiuzhaigou Valley, and extends northwards to the Hadapu station of the Lanzhou-Chongqing railway which is under construction.
