摘要

建筑物挠度的消除包括用活塞液压千斤顶不均匀地抬高建筑物。由于技术原因，在脱轨过程中，一堆平行六面体钢构件位于千斤顶下。叠层对支撑刚度有决定性的影响。设计并进行了平行六面体单元叠加加减力试验。在试验的基础上确定了三个特征相。各阶段最大刚度分别为理论刚度的13.1、63.1和10.1%。

Examination of stiffness of stack of steel elements forming part of supports used for removal of building deflections

The removal of building deflections consists of uneven raising of buildings with piston hydraulic jacks. A stack of parallelepiped steel elements is situated under jacks during defl ection removal for technological reasons. The stack has decisive influence on the stiffness of the supports. Tests of the stack of parallelepiped elements loaded with increasing and decreasing force were designed and carried out. Three characteristic phases were identified based on the tests. The maximum stiffness in particular phases was, respectively 13.1, 63.1 and 10.1% of theoretical stiffness.

期刊介绍： Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
