摘要
本文分析概括了扭工字体过去和现在的研究成果,把对该块体的研究分为两个阶段,即以块体稳定性研究为主的第一阶段(六、七十年代)及以块体结构强度为主的第二阶段(八十年代以来)。在总结各方面研究成果的基础上,可以看出,扭工字体的研究受到科研、设计、工程等单位的密切重视,尽管研究方法、手段、标准尚缺乏同一性,结果有时也存在差异,但对于工字体在实际应用中应注重的一些方面,科研人员基本上达到了共识。文中对我国如何应用扭工字块体提出了一些建议。
Both the past and present research work on dolosses are summaried and analysed. The research work on dolosses is divided into two stages. The first stage (from the 60s to the 70s) was characterized by the research into the stability of dolosses while the second stage (since1980s) has been characterized by the research into the structural strength of dolosses. It can be known from the summing-up of various research results on dolosses that much importance has been attached to the research work on dolosses by various researchers, designers and construction companies, and though the methods, means and criteria adopted for the research work were not the same and the results thus obtained sometimes varied, a common understanding has been reached on some aspects which should be taken into due account during the practical application of dolosses. Recommendations on how dolosses should be employed in China are also given.
