Report from June 1994

The Workshop on Remedial Techniques for the Qinghai-Xizang (Tibet) Highway in Permafrost Regions was held on 13-15 April 1994, at the State Key Laboratory of Frozen Soil Engineering, LIGG, Chinese Academy of Sciences. Thirty experts and scientists participated in this workshop. Several valuable proposals for the remedial scheme and design principles for the highway were presented and discussed. This workshop is one of the most important preparations for carrying out the remedial project on the Qinghai-Tibet Highway.

Progress on the permafrost and global climate change research program is as follows:

  • Chapters for the China report to the IPCC "Evaluation of the influence of climate change on environment in China" have been prepared as follows: Chapter 11: The influence of climate change on permafrost zones in China; Chapter 12: The influence of climate change on glaciers in China; and Chapter 13: The influence of climate change on snow cover in China.
  • The ground temperature monitoring system along the Qinghai-Tibet Highway has been set up.
  • A 100-m-deep and a 200-m-deep bore hole for monitoring ground temperature will be set up on the Qinghai-Tibet plateau in 1994.
  • Investigation of the concentration of CH4 and CO2 will be carried out along the Qinghai-Tibet Highway

Volume 2 of the Proceedings of the Sixth ICOP, containing 98 reports, papers and poster abstracts, was shipped in late April to every registered participant, perexcept accompanying persons. Any participant who has not received Volume 2 should contact the Chinese Organizing Committee.

Report from December 1994

The First National Youth Workshop on Cold Regions Environment and Engineering was held at Lanzhou, China, 2-6 September 1994. It was organized by the State Key Laboratory of Frozen Soil Engineering, Lanzhou Institute of Glaciology and Geocryology, the Chinese Academy of Sciences and the Chinese Society of Glaciology and Geocryology. More than 40 participants from 15 institutes, universities and organizations attended this workshop. The young researchers and engineers exchanged ideas and discussed their achievements and experience in research on cold regions environment and engineering. The proceedings of this workshop, which includes 39 papers, has been published in Chinese. The Chinese Youth Society of Cold Regions Environment and Engineering was founded during this workshop. It was decided that this workshop will be held once every two years, and the next workshop will be held at Dalian, China, in 1996. The First Chinese National Symposium on Frozen Soil and Ice Mechanics will also be held at Dalian 5-9 June 1995. This symposium is being organized by the State Key Laboratory of Frozen Soil Engineering. the Dalian University of Technology, and the Monitor Centre of sea Environment, the State Sea Bureau. The first announcement of this symposium has been sent out.

Activities at the State Key Laboratory of Frozen Soil Engineering continue with numerous test results being published. The CT scanning technique has seen its first successful use to observe the development of micro-cracks in frozen soil and ice specimens during deformation. Three-point bending tests on a frozen beam were successfully conducted in this laboratory, and the test results will be published soon.

Research and planning of future programs continue at the Plateau Station. These include studies of periglacial phenomena. monitoring of borehole temperatures (based on 20 years of records and a 203-m-deep borehole), moisture and heat flow in frozen ground, permafrost ecology, and the effects and measurement of greenhouse gases. Details about these activities are available from Zhao Xiufeng at the LIGG.
