摘要

筒仓在设计、安装和运行过程中存在各种缺陷和损伤,影响筒仓结构构件的应力应变状态和耐久性。及时检查和确定结构和整个场地的结构要素的技术条件,将确定其进一步安全操作的可能性,或通过确保结构的结构安全和可靠性来恢复操作特性的需要。因此,制定局部损伤筒仓圆形钢筋混凝土构件的设计方案、应力-应变状态、预期寿命和进一步配筋的计算方法具有重要意义。结构元件的不当维护和操作,以及未来设计和安装的错误,导致无法正常使用,有时会发生紧急情况。制定加强现有结构的项目是一件非常负责任的事情。加固现有地基最常见的解决方案是增加地基垫层的支撑面积,但在紧凑的建筑物中,这并不总是可行的。这项工作的目的是确定筒仓建筑结构的技术条件和在PC里拉中执行的计算结果,为具体实例提供加强基础的选择。给出了筒仓钢筋混凝土整体基础的结构解决方案,以及由结构技术条件确定的主要缺陷和损伤。为进一步保证结构的安全运行,建议采用胶粘复合胶带对墙体基础进行加固,并按照结构加固的附加工作设计,通过控制桩的生长对基础进行加固。如果按照有关加强和坚持安全可靠的建筑及构筑物运作的最新建议,建筑构筑物的进一步运作将是安全的。

ASSESSMENT OF CARRYING CAPACITY OF THE ROUND IN PLAN REINFORCED CONCRETE FOUNDATION FOR THE SILO
During the design, installation and operation of silos, they have defects and damage of various kinds, which affect the stress-strain state and durability of structural elements. Timely inspections and determination of technical conditions of structural elements of the structure and the site as a whole, will establish the possibility of its further safe operation or the need to restore operational properties by ensuring structural safety and reliability of structures. Therefore, the development of design schemes, methods of calculating the stress-strain state, life expectancy and further reinforcement for round reinforced concrete elements of silos with local damage, is quite relevant. Improper maintenance and operation of structural elements, as well as errors in the design and installation in the future lead to unusable for normal operation and sometimes an emergency. The development of projects to strengthen existing structures is a very responsible matter. The most common solution for strengthening existing foundations is to increase the area of support of the foundation cushion, which is not always possible in a compact building. The purpose of the work is to determine the technical condition of the building structures of the silo and the results of calculations performed in the PC Lira, to offer options for strengthening the foundation on a specific example. Structural solutions of the reinforced concrete monolithic foundation of the silo, the main defects and damages determined by the technical condition of the structure are given. For further safe operation of the structure, it is recommended to reinforce the wall foundations by gluing composite tapes and perform reinforcement of the foundations by controlling the growth of piles in accordance with the additional working design of the structure reinforcement. If the latest recommendations on strengthening and adhering to the safe and reliable operation of construction and structures are followed, further operation of building structures will be safe.
