| 6. | Exemplified by the application of shallow seismic reflected wave technique to the exploration of haicang bridge in xiamen , this paper makes a preliminary discussion on various aspects of the application of shallow seismic reflected wave technique to the exploration of bridge site in water area 摘要结合浅层地震反射波法在厦门海沧大桥勘探中应用,对在水域进行桥址浅层地震反射波法勘探中的各方面作一探讨,浅谈一些认识和体会。 |
| 7. | In comparison with the apups , the results have shown that the surface states of the hollow site are in good agreement with the experiment . so we concluded that the hollow site model is favourable for the gaas ( 113 ) ( l xi ) surface and the bridge site model should be e xcluded . 3 3 .其他工作除此之外,论文还对铅盐pbte 、 pbse 、 pbs ( 001 )表面电子结构, ybco超导体表面氧特性、金属ti和ni在金刚石表面的吸附和扩散等特性进行了研究。 |
| 8. | Based on wind speed observation record with drawback , it is proved that the exponent expressing terrain roughness can be calculated according the monthly maximum wind speed records at various height levels . wind characteristics of bridge site are determined by statistical method 针对桥址区风速观测记录的特点,证明了利用不同高度处月最大风速记录推算地表粗糙度影响系数的可行性,并对通过最小二乘拟合得到的地表粗糙度影响系数进行统计分析,最终确定桥址区风特性。 |
| 9. | According to the result of physical modeling , the regression equation about the decrement of tidal bore height , the percentage of water - resisting area and the distance away from the upstream bridge site is constructed in this paper , the regression equation can be applied in the impact which bridge has on the tidal bore height in qiangtang esturary 根据模型试验结果,建立了涌潮高度的减小值与中潮位桥墩阻水面积百分比和上游离桥址距离的多元回归方程,可供钱塘江河口建桥对涌潮高度的影响计算参考使用。 |
| 10. | It is local impact that bridge being built has on the shape of tidal bore , and this local impact can be recovered in the place which is 300 - 500 long upstream bridge . the impact that bridge being built has on the intensity of tidal bore depends on the water - resisting area of bridge . generally the more water - resisting area is and the nearer the place is away from the bridge site , the more impact is on the intensity of tidal bore 建桥对涌潮形态的影响是局部的,在桥上游300m 500m的范围内基本可以得到恢复;建桥对涌潮强度的影响主要取决于桥墩阻水面积,一般来讲,阻水面积越大,位置离桥址越近,对涌潮强度的影响亦越大。 |
