典型古建筑保护中的基础性问题研究

RESEARCH ON THE BASIC PROBLEMS IN OLD BUILDING PROTECTION

讨论了古建筑修缮原则中有关其结构方面的问题。整理1:100应县木塔比例模型风洞试验,得到木塔开窗和闭窗两种状态的风压体型系数;分析了木塔院区塔基土的工程物理性质和力学性质;得出了木塔的基础结构状况。云冈石窟存在多种病害,但最主要包括水害、裂隙发育和岩体崩塌、风化、环境污染,对这些病害的防治与治理方法是此类文物建筑的长期重点研究与实施内容。平遥古城墙为土筑墙体,年代久远,自然、人为损伤不断,坍塌时有发生,计算分析了几类典型损伤导致的墙体破坏特点。

The repairing principle problems of old building structures are discussed. The wind tunnel tests were carried out on 1:100 scale wooden tower model by selecting two wind speeds and two cases (window opened and closed), from which the octal wind pressure coefficient were derived. Consequently, the engineering physical property, mechanical property by specimen analyses, standard infiltrating tests and calm force touching surveying tests are obtained. The foundation composition and delamination composition of the tower courtyard foundation by resistivity tomography with surface electrode arrays are explored and attained. There are various diseases in Yungang Grottoes, including water harming, cracks and collapses of rock, the breeze causing and pollution of the environment. Thusly, a long-term research work is needed for the prevention and cure. The pingyao ancient city wall is a combination wall of the soil and brick. For the long age, there are collapsing affairs usually by nature and artificial hurting. In order to do the research, the wall-body breaking characteristics are gotten by computing several typical wall models.
