MethodWiththe evaluation method in《GB/T18005-1999 Chinese Quality Grade Assessment for Scenic Resources of Forest Park》,the biological,hydrological,geographic,cli matic and humanismresources of Mopan Mountain national forest park in Yuannan Province were assessed through the quality assessments for ecotourismresources and regional environment,assessment for tourismdevelopment condition and quality grade assessment for integrated resources to knowabout the quality condition of ecotourismresources of Mopan Mountain national forest park.

方法利用《GB/T18005-1999中国森林公园风景资源质量等级评定》中的评价方法，通过生态旅游资源质量评价、区域环境质量评价、旅游开发条件评价和综合资源质量等级评价对云南磨盘山国家森林公园的生物资源、水文资源、地文资源、天象资源和人文资源进行评定研究，进而了解磨盘山国家森林公园生态旅游资源的质量状况。

This method is about which bridge engineering quality is integrally evaluated by using the fuzzing mathematical, hi the course of fuzzy integrated evaluation, firstly, the specialists weight coefficient is defined and the score of qualitative indexing is calculated. Moreover according to the practical situation for project, the specialists present the weight coefficient for subdivisional project and partitioned project.

在建立模糊综合评定模型的过程中，首先确定专家的权重，计算定性指标的得分；再由专家根据工程实际情况给出分项、分部工程的权重，根据分项工程的评分，计算其隶属于评定等级的隶属度；最后由模糊数学模型对桥梁工程质量进行模糊二级综合评定，得出最终的评定结果。

4 Results of nondestructive test for weld joints shall be graded according to JB 4730. Following requirements shall be met: a For radial test, quality grade of radial transillumination can't be lower than Grade AB, and that of weld joints shall meet table 10; b For supersonic test, approval standard for weld joints are as follows: 1 For weld joints of 100% supersonic test, grade Ⅰ. 2 For weld joints of local supersonic test, grade Ⅱ. c For magnetic particle test and penetration test, grade Ⅰ.

7.5.4 管道焊接接头的无损检测应按 JB 4730 进行焊缝缺陷等级评定，并符合下列要求： a 射线检测时，射线透照质量等级不得低于 AB 级，焊接接头经射线检测后的合格等级应符合表 10 的规定； b 超声波检测时，管道焊接接头经检测后的合格标准如下： 1 规定进行 100%超声波检测的焊接接头 I 级合格； 2 局部进行超声波检测的焊接接头 II 级合格； c 磁粉检测和渗透检测的焊接接头 I 级合格。

The correlation between pilling grade assessed by Bp network and that by skilled person is 0.97, and the evaluation correctness is 92%.

Bp网络评定结果与主观评定结果的相关系数是0.97，等级评定的正确率是92％；自组织神经网络的评定结果与主观评定结果的相关系数是0.95，等级评定的正确率是84％。

It was considered most appropriate to use the results from 1 of these series for the further analyses, rather than aeraging the 2 or reassessing discrepant ratings, because the consistency between the ratings for different patients is likely to be higher during a gien series.

通过进一步的分析，用系列1的结果被认为是更加恰当的，这通常要优于系列2或是对矛盾的等级值进行再次评定。因为对不同病人之间的等级评定的一致性，持续用特定的系列可能更高。

Then, safety analysis method was constituted considered the typical damage of concrete beam bridge. 5. By amending the reduction rate of loading capacity used in Code for Maintenance of Highway Bridges and Culvers (JTG H11-2004), a new reliable index is presented in the same safety standard to reflect the relation between load and resistance. According to the basic principal of calibration method, the recommended gradation index was computed under various factors such as different load combinations, vehicle operating status and different failure modes. With these calculated numerical values, the calculated reliability indexes standard for the estimation of safety degree of in-service concrete girder bridge members was ultimately obtained.6. Based on the related standards and results on crack and displacement that cannot continue to loading at home and abroad, the evaluation grade of the concrete beam bridge is proposed by analogy.

针对材料和构件损伤对混凝土梁式桥抗力的影响，基于材料和构件层次典型损伤的修正计算公式，在结构既有以及时变抗力评估的概率模型基础上，通过误差传递公式获得抗力统计参数，对抗力进行修正，构成了考虑混凝土梁式桥典型损伤的安全性分析方法。5、依据校准法原理，将《公路桥涵养护规范》(JTG H11-2004)中不同类别承载力下降率转化为修改分项系数，分别计算了轴心受压、轴心受拉、受弯、大偏心受压、受剪构件在各种情况下的可靠指标，根据破坏类型对校准结果进行分析，提出了基于可靠度的公路混凝土梁式桥安全性评定等级。6、基于不能继续承载的裂缝和位移的相关国内外规范和研究成果分析，通过类比提出了混凝土梁式桥不能继续承载的裂缝和位移评定等级界限。
