| Abstract (English): |
Collapse of high falsework occurs frequently, and human errors are the main cause. Due to the low correction efficiency, falsework is usually in commission with errors. Bringing new ideas and technologies into the design of falsework is essential. 'Error-tolerant design', which has generated effective impacts in road engineering, was introduced into the design of falsework, and error-tolerant high falsework (ETHF) was developed. The occurrence pattern of human error was obtained in terms of in-situ investigation, and identification method of intractable errors was given. The performance functions and safety standards of the ETHF were described, and an optimization design method which considers intractable errors was proposed to eliminate the side effects of errors and satisfy the requirements of safety, serviceability and cost-efficiency. The case study showed that the reliability index of the optimized ETHF was 3.39 and the amount of steel of the optimized structure was reduced by 19.5%. The goal of "error-tolerant design" was attained. [ABSTRACT FROM AUTHOR] |

高大模板支架坍塌事故不断发生，人为错误是主要原因，但改错效果不理想，支架往往带错工作，迫切 需要新的设计思想和技术。该文借鉴道路工程中已取得明显效果的"容错设计",将其引入模板支架的设计中， 提出一种新的容错模架。在通过现场调研掌握人为错误发生规律的基础上，给出不易改正的顽固人为错误的辨识 方法，研究容错结构的功能函数和安全水准，提出考虑顽固人为错误发生的优化设计方法，以消除错误的负面影 响，达到安全、适用和经济的目标。算例表明，经优化后的结构，容错模架的可靠指标为3.39、用钢量节省19.5%， 达到了“容错设计"的目标。 [ABSTRACT FROM AUTHOR] |
