摘要：

水运工程在用结构物的诊断、检测与加固技术是确保建筑物运行安全的重要手段,也日益成为工程建筑物使用中急需的技术和科研热点问题。以建成使用不到3年就发生异常开裂的井字形滑道轨道梁为研究对象,采用"有限元模拟-检测验证"方法,对其破损机理进行了研究,数学模型研究成果与工程检测的结果基本吻合,据此提出了安全、可行的针对性加固方法。

The technology of detection,diagnosis and reinforcing of maritime structures being in operation is the important measures to insure their safe operation during their service life,which becomes increasingly the urgently needed techniques and hot topics for scientific research.The paper takes the rail girders of intersecting parallel pattern for a slipway as s studying object,which had been exceptionally cracked in less than three years after the slipway was put into operation and conducts re-searches of the mechanism of the cracking by using the "finite element simulation-examination confirmation" method.The re-sults ofmathematical modeling and the tested results are fitting well,on the basis of which,a safe and feasible target-oriented reinforcing method is proposed.
