探测冰盖和多年冻土层的融冰探头研发

The exploration of ice sheets by melting vertical holes into the ground has some tradition in terrestrial glaciology. Such probes have been used since the 1960's to investigate the vertical structure of the ice in Greenland and Antarctica and in alpine glaciers. In this paper we look into the possibility to develop similar devices for use on extraterrestrial icy bodies, like e.g. the polar areas on Mars or the icy satellites of the outer solar system. We report on some basic experiments performed in the cryo-vacuum laboratory of the Space Research Institute of the Austrian Academy of Sciences, Graz. In these experiments the penetration of a simple melting probe into compact and porous water ice (with a snow-like texture) was monitored, both under vacuum conditions and under air pressure. The observed penetration speeds for a given power supply are compared with a simple mathematical model. We conclude that a miniature melting probe with small overall dimensions and a reasonable power demand could well be part of the payload of a future planetary mission, for example to the poles of Mars. Such missions are currently under discussion in several space agencies. Moreover such probes could also e? ectively be used in terrestrial environments. A possible design is presented at the end of the paper.     

光学探生仪研制

Seismic demand of plan-asymmetric structures: a revisit

In view of the recognition of the importance of the interdependent behavior of strength and stiffness of walltype structural elements,the seismic demand of plan-asymmetric systems is revisited.Useful strength distribution strategies,i.e.,’Center of Strength-Center of Mass(CV-CM) coinciding’ and ’Balanced Center of Strength-Center of Resistance(CVCR)’ are adopted.Design charts for the seismic demand of classical uni-directionally and bi-directionally asymmetric systems are developed in a simple unified format.A conceptual framework is also outlined to conveniently apply the design charts.Illustrations are included to explain the use of the current recommendations in practical design.The study also highlights the relative performance of ’CV-CM coinciding’ and ’Balanced CV-CR’ criteria.

桩筏共同作用的改进Geddes计算模型与变刚度调平设计

Geddes应力法虽然实现了桩与桩之间的相互作用,但由于没有考虑筏板的刚度,无法实现桩与筏板的共同作用。对Geddes模型进行了改进,以实现桩与筏板的共同作用。通过一工程实例,验证了此改进模型的正确性,并利用此模型,阐述了通过调整桩的疏密布置进行设计的概念和方法,达到减小差异沉降、防止结构产生次应力和节约工程造价的目的。
