消防救援队伍战勤保障预案是针对特定情况可能发生的火灾及其他灾害事故,对灭火救援有关保障问题预先安排的作战文书,是实施灭火救援行动的重要依据。编制一个科学合理、内容翔实、贴近灾害现场实际的战勤保障预案,有利于指挥员在灾害现场临阵不乱,快速进行力量部署,准确科学进行灭火救援指挥,将灾害损失降低到最低限度。高原高寒地区因其海拔高、气候寒冷等因素,给消防战勤保障工作带来一定的困扰。因此,加强高原高寒地区战勤保障预案编制意义重大影响深远。改革转制以来,消防救援队伍战勤保障工作坚持“平时战时相结合、自保联保相统筹、物保技保相配套、保障管理相协调”的原则,逐步建立完善了消防救援队伍战勤保障体系。战勤保障预案制定是强化前置保障的重要前提,也是提升队伍战勤保障能力的重要方式方法。因此,本文从预案制定的意义和原则着手,对高原高寒地区的战勤保障预案制定进行研究。

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第5期8卷 682-692页

作者： zhang zhi-cheng XIE Xu zhang He CHEN Heng-zhi Department of Civil Engineering Zhejiang University Hangzhou 310027 China

A convenient approach is proposed for analyzing the ultimate load carrying capacity of concrete filled steel tubular (CFST) arch bridge with stiffening girders. A fiber model beam element is specially used to simulate the stiffening girder and CFST arch rib. The geometric nonlinearity, material nonlinearity, influence of the construction process and the contribution of prestressing reinforcement are all taken into consideration. The accuracy of this method is validated by comparing its results with experimental results. Finally, the ultimate strength of an abnormal CFST arch bridge with stiffening girders is investigated and the effect of construction method is discussed. It is concluded that the construction process has little effect on the ultimate strength of the bridge.

It is a very important issue for us to explore the effects of the marriage to life. In recent years, many scholars have proved that the marriage can lengthen life-span from different angles. With the development of theory of dependence random variables, we discuss the effects of the marriage to life and provide a mathematical basis of the idea that the harmonious marriage can lengthen life-span in this paper. Meanwhile, we analyze the impact of the marriage on life on the basis of the net single premium.
