This paper calculates the structural reliability of typical members of reinforced concrete in harbour work. The probability analysis approximate method and the Chinese Norm JTJ 220-82 are adopted. The resulting structural reliability indices are close to the target reliability indices, provided by the draft of the Chinese "Unified Standard for Building Structures Design" (Draft), parameters used in the calculation is slightly conservative than usual.

This paper calculates the structural reliability of typical members of reinforced concrete in harbour work. The probability analysis approximate method and the Chinese Norm JTJ 220-82 are adopted. The resulting structural reliability indices are close to the target reliability indices, provided by the draft of the Chinese "Unified Standard for Building Structures Design" (Draft), parameters used in the calculation is slightly conservative than usual. The reasons of this treatment are stated briefly in this paper.

本文用近似概率法按现行规范JTJ220-82分析了港口工程钢筋混凝土典型构件的可靠度。计算结果可靠指标接近“建筑结构设计统一标准(草案)”规定的目标可靠指标。文中所用的参数略偏于保守,简述了参数选择的理由。

Based on the background of massive structures, such asbridge, harbour works, dam, offshore engineering etc, this paper discussesthe following problems: First of all, the relationship between input-output signals and phy-sical parameters is established, and a mathematical model for the iden-tification of structure parameters is discussed. Second, the elemental theory of condition monitoring and faultdiagnosing for structures is discussed, covering observability, identi-fiability, ill-posed problem, existence...

Based on the background of massive structures, such asbridge, harbour works, dam, offshore engineering etc, this paper discussesthe following problems: First of all, the relationship between input-output signals and phy-sical parameters is established, and a mathematical model for the iden-tification of structure parameters is discussed. Second, the elemental theory of condition monitoring and faultdiagnosing for structures is discussed, covering observability, identi-fiability, ill-posed problem, existence and uniqueness. Third, a solution is given for the inverse problem, that is a solu-tion of physical parameters, which contain unknown variables (M,C,K).To solve the variables, the inner product matrix is adopted. And finally, a method is suggested about the condition monitoringand fault diagnosis of the system, that is, the input signals of systemis excited by means of a series of rockets.

本文论述用动力学方法研究大体积结构(如桥梁、海港、水坝、海洋工程)状态的变化和故障的诊断问题,为评估工程结构的寿命和维护管理提供参考依据。文中首先建立结构参数识别数学模型,其次论证结构状态监测与故障诊断的基本理论,最后给出一种反问题的解法,并建议一种用一组火箭激励的监测与诊断方法。

Objective:To study and compare the effects and features of long term voyage on psychological health of sailors in naval ship and nuclear-powered submarine, so as to provide scientific basis for enhancing the level of psychological health of sailors during long term voyage.Methods: The subjects were divided into naval ship group and submarine (nuclear-powered) group,and the controls included harbour working group and the Chinese armymen's normal value.

Objective:To study and compare the effects and features of long term voyage on psychological health of sailors in naval ship and nuclear-powered submarine, so as to provide scientific basis for enhancing the level of psychological health of sailors during long term voyage.Methods: The subjects were divided into naval ship group and submarine (nuclear-powered) group,and the controls included harbour working group and the Chinese armymen's normal value. The psychophysical state of sailors was tested by EPQ, SCL-90 and PSSG. Results: (1) Personal feature: As compared to pre-voyage, N score in naval ship group after voyage increased by 41.7% (P<0.05), and in submarine group increased by 57.3% (P<0.01), L score also increased but E score decreased (P<0.05). (2) Psychological health: The factorial scores of depression, anxiety in naval ship group and the factorial scores of somatization,obsessive compulsive, interpersonal relation, depression and anxiety in submarine group after voyage were much higher than those before voyage and the armymen's normal value (P<0.01) (3) Psychological stress: TS, NE, PC scores in naval ship group after voyage were increased (P<0.05), TS, NE scores in submarine group were very significantly increased (P<0.01), NC score was also increased (P<0.05).Conclusion:Long term voyage of naval ship and nuclear-powered submarine with different special circumstances for sailors'living and working would induce marked effect on the state of psychological health of the sailors.However, the features of behavior disturbance and the falling degree of psychological health level of them may be different.

目的 :比较研究长时间水面和水下航行对艇员心身健康水平的影响及其特点 ,为提高长航艇员的心理健康水平提供科学依据。方法 :(1)研究对象分水面舰艇组、核潜艇组 ,对照组包括岸勤组和中国军人常模。 (2 )采用艾森克个性问卷 (EPQ)、症状自评量表 (SCL - 90 )及团体用心理社会应激调查表 (PSSG)在长航前后对艇员进行测评和结果比较。结果 :(1)个性特征 :水面舰艇组航后内 -外向得分较航前增高 4 1.0 % (P <0 .0 5 ) ;核潜艇组航后内 -外向得分较航前增高 5 7.3% (P <0 .0 1) ,并有精神质得分降低和掩饰倾向得分增高 (P <0 .0 5 )。 (2 )心身健康评分 :与军人常模比较 ,水面舰艇组航后忧郁、焦虑因子分非常显著增高 (P <0 .0 1) ,核潜艇组航后躯体化、强迫、人际关系、忧郁、焦虑因子分非常显著增高 (P <0 .0 1)。 (3)心理应激评分 :水面舰艇组航后心理应激总分、负性情绪分、正性应对分增高 (P <0 .0 5 ) ,核潜艇组航后负性应对分增高 (P <0 .0 5 ) ,而心理应激总分、负性情绪分则非常显著增高 (P <0 ....
