| 3. | 2 . the ground pressure and lining stress of lining of entrance increases as gradient of up - slope increases ( 2 )洞门段围岩压力及衬砌结构受力随仰坡坡度增大而增大。 |
| 4. | 4 . the characteristics of stress distribution in entrance structure prove that spatial effect occurs within certain length ( 4 )洞门段结构受力分布特征表明洞口段空间效应长度是一定的。 |
| 5. | The main characteristics are as follows : l . the stress characteristic of lining of entrance corresponds with that of shell structure 其主要特征为: ( 1 )洞门段衬砌结构受力特征与壳体结构受力特征相符。 |

| 7. | While the brand - new types of portal has no standard draft for reference , as a result , the study on stress characteristics of brand - new portal is of essential importance 而作为新型洞门型式没有标准图可以参照,研究新型隧道门结构的受力特征对于新型洞门的设计施工是相当必要的。 |
| 8. | Many years so far it is qualitatively regarded that tunnel portal stress is under complex 3 - dimensional state , and it is designed according to standard draft 多年来,隧道洞门结构受力特征只是定性地被认为结构处于复杂的三维状态,隧道洞门设计只是经验性地采取照搬标准图的模式。 |
| 9. | In this paper it first suggests 3 types of brand - new portal to be investigated in the light of landscaping and environment nursing , namely up or down bamboo - truncating portal and arc retaining wall portal 本论文首先从景观和环保意义出发提出了要研究的三种新型洞门型式:正削竹式、倒削竹式洞门和弧形挡墙洞门。 |
| 10. | In china , traditional portal of railway tunnel can be sorted as three types - origin , modified and special types , inclusive of 16 kinds on basis of the characteristic of terrain , basically they are of end wall and post type 我国传统铁路隧道洞门根据地形特点分为基本型、变化型、和特殊型三大类十六种形式,但始终脱离不了端墙、柱式的形式。 |
