Analyzing Design Mistakes in the “Bean Curd Dregs” Engineering Design

Zhang Zhaoshen

Strategic Study of CAE 2004, Volume 6, Issue 11, Pages 8-19

Abstract:

The paper discusses the omission in analyzing the worst stressed state and the mistake in strength and stability checking computations method for compression and bending member, by analyzing the available construction calculation analysis program function, in order to approach the reason of Qijiang arch bridge breakdown. Especially the paper queries whether there exists the bend section modular calculating method for dumbbell or round end rectangular section arch rib, to prove the existence of a lot of unsafe factors in the steel pipe-concrete arched bridge. Finally the paper recommends, the designer to change the idea of unilaterally chasing new and strange into the principle of safe, durable and useful,so as to design and build the structure that will never break down for a century.

Analysis of synergy degree and its influencing factors in hydropower EPC project management

Jiwei ZHU, Hua GAO, Jiangrui WANG

Frontiers of Engineering Management 2021, Volume 8, Issue 3, Pages 402-411 doi: 10.1007/s42524-020-0098-0

Abstract: The mechanism and factors that influence the degree of management synergy are analyzed on the basis ofanalysis is utilized to identify the key factors that affect the synergy degree.Results show that the order degree of each subsystem presents a steady upward trend.Specifically, the order degree of the subsystem at the trial operation stage is low, which is the majorrestriction on the further improvement of the synergy degree of EPC project management.
