| 4. | Recently , she has been romantically linked with paul wong , a member of the hong kong - based rock band beyond 她说:我希望多方面尝试不同的角色,创造多姿多彩的生命。 |
| 5. | Arch dam , which is fastened to the base rock , is a high _ order , hyperstatic , spacial body case structure . it has not only arch function but also girder function , but its main loads are passed to each dam abutment by means of arch function 拱坝是固结于基岩的高次超静定空间壳体结构,既有拱作用又有梁作用,其主要荷载是通过拱的作用传到两岸坝肩。 |
| 6. | Arch dam , which is fastened to the base rock , is a high _ order , hyperstatic , spacial body case structure . it has not only arch function but also girder function , but its main loads are passed to each dam abutment by means of arch function 拱坝是固结于基岩的高次超静定空间壳体结构,既有拱作用又有梁作用,其主要荷载是通过拱的作用传到两岸坝端。 |
| 7. | ( 3 ) generally , dam and base are operated in material viscidity status . by studying on the creep model of dam concrete and base rock , and combined them together , the coupling model of these factors is bringing forward ( 3 )通过研究坝体混凝土徐变模型和坝基岩体的蠕变模型,并将两者有机结合,分别针对混凝土重力坝和拱坝,提出了考虑坝体徐变和坝基蠕变相互作用的组合模型。 |
| 8. | Using the repetition data from the leveling circuit , which is composed of the spots at the measurement field in the hefei deformation observatory and the base rock at the neighborhood of the measurement line , we estimate the degree of stability of each spot 摘要以合肥形变台短水准测量场地各基岩点与检测线路端点(基岩)组成水准环线进行连测,利用重复观测资料,估算各点稳定度。 |
| 9. | Include the following several respects basically : ( 1 ) according to blast dynamics theory , research calculate gather can powder bag cut base rock form in the range of the crack when blowing up individually , analyse that proving can gathers the function of cutting the rock of powder bag 基本包括以下几个方面: ( 1 )根据爆破动力学理论,研究计算了单个聚能药包爆破时切割基岩形成裂缝的范围,分析论证聚能药包切割岩石的作用。 |
| 10. | On one hand , the stress in mass concrete is caused because of the difference between internal temperature and external one . on the other hand , with the concrete solidifying , the tensile stress will appear due to concrete ' s shrinkage restrained by base rock 大体积混凝土一方面由于内外温差而产生应力,另一方面,由于混凝土的凝固,收缩变形受到约束,混凝土会产生拉应力,一旦温差引起的应力和收缩变形引起的应力超过同龄期混凝土的极限抗拉强度,混凝土就会产生裂缝。 |
