| 4. | In the experiments the fixed supports of the bottom of the columns are simulated creatively and the reaction of forces is tested 对这样的大尺寸构件,该试验还开创性的利用试验验装置进行框架柱底嵌固进行模拟,并测出了柱底反力。 |
| 5. | The spring elements are adopted to simulate the link between the bridge foundation and soil , and the longitudinal restraint of tracks on the superstructure of bridges 摘要采用弹簧单元模拟地基对桥梁基础的嵌固以及轨道桥面系对梁体的纵向约束作用,建立桥梁轨道桥面地基共同受力的全桥整体模型。 |
| 6. | The effect of such factors , as the frozen soil degradation , the soft effect of restraints of soil to bridge foundation , on the safety and seismic response of railway bridges are considered and simulated 结果表明,当冻土退化而导致地基嵌固作用降低时,桥梁墩身的地震弯矩减小,桩身弯矩和墩顶位移增大。 |
| 7. | Sprayed concrete fixed the soil ; anchor arms were embedded deeply in the soil , active supported the soil , and acted with the soil , all of those effective kept and increased the strength of the soil 喷射混凝土与土层面产生嵌固效应;锚杆深固于土体内部,主动支护土体,并与土体共同作用,有效保持和提高围土强度。 |
| 8. | ( 3 ) rock bolts are used as an extension of the supporting piles . this structure solves the embedding problem of cantilever pile and is newly applied in foundation trench in china . no environment contamination appears in this old crowed town because no detonation or mechanical drilling ( 3 )利用岩石锚杆作为围护桩的延伸成功地处理悬臂桩嵌固的问题,该结构方式的应用为国内首例,避免了在旧城镇老房屋密集区基岩爆破和机械成孔对周围环境的影响和污染。 |
| 9. | A calculation method on the energy dissipation of semi - rigid steel frame is presented and it is proved that many factors , such as beam end - fixity , viscous damping , fundamental frequency of steel frame and frequency of excitation , etc . have close relationship with the energy dissipation ability of semi - rigid steel frame 5本文总结了半刚性连接框架二阶弹塑性分析方法和塑性铰分析方法,提出了半刚性连接框架耗能计算的公式。研究表明,半刚性框架耗能的大小与连接的嵌固程度、结构的阻尼、自振频率等均有很大的关系。 |
| 10. | Various distribution models of the coefficient of subgrade reaction can be considered after the two - parameter method is employed . the commonly used " k " method , " m " method , and " c " method can easily be obtained from it . thus , the solutions of the internal force along the studied stabilizing piles have more ordinary representation by the two - parameter method 2 、引入双参数法后,能够考虑土抗力的多种分布模式,常用的m法、 k法、 c法均被涵盖在其中,从而在计算桩的嵌固段内力分布时得到的计算表达式更具有代表性。 |
