| 2. | Some suggestions were proposed to the calculation of earth pressure in gravity retaining wall design 对重力式挡土墙设计中土压力的计算具有一定参考价值。 |
| 3. | Abstract : gravity retaining wall used for landslidecontrol is wastful in materials exactly , for its quantity of masonry is too much 文摘:用于治理滑坡的重力式挡墙,由于其圬工量太大,材料确有浪费。 |
| 4. | Consequently , the optimum design of gravity retaining walls with balancing platform are of great engineering significances and potential economic effect 因此,衡重式挡土墙的优化设计研究具有重要的工程实际意义及潜在的巨大经济效益。 |
| 5. | However , the routine design is characterized by vast and repeated calculation , and difficult in finding an economic and sound design . and the existing cad programs are mostly limited to earth pressure calculation and design of gravity retaining wall 但其常规设计计算量大、重复劳动且难以得到经济合理的设计方案,而现有挡土墙优化辅助设计程序多局限于土压力及重力式挡土墙的计算。 |
| 6. | The pile building enclosure with two or three bracing pieces and the gravity retaining wall are particularized as example in this paper . from the antithesis with datum practically measured , it indicates that the fem which is adopt by this paper is logical and feasible 本文分别对两道和三道支撑的桩(墙)式围护结构及重力式挡墙围护结构基坑工程进行了有限元模拟计算,根据与实际监测资料的对比分析,表明本文所采用有限元方法是合理可行的。 |
| 7. | Fifteen degree or so of nail and anchor inclination is the optimized . some certain value of nail space is proposed by which soil nailing structure and earth nail wall can be differentiated . the method to analyze the gravity retaining wall is applied to earth nail wall 建议土钉和锚杆倾角采用15左右为宜;当土钉间距小于某一值,或土钉密度大于某一定值时,土钉支护形成重力式挡土墙,即土钉墙,此时可以采用重力式挡土墙的分析方法对土钉支护进行分析。 |
| 8. | The numerical results show that the horizontal variation of response acceleration of gravity retaining wall is quite small since its lateral rigidity is large enough , the response at a given height level can be considered as the same , the maximum accelerations at different heights on the central vertical line can describe the distribution of earthquake load along the wall height in static analysis very well 数值结果显示,重力式挡土结构刚度很大,地震加速度反应在水平方向差异很小,可看作是同步的,可取中心线上各点最大加速度来描述静力法中地震作用沿高度的变化规律。在沿墙高度方向,加速度分布不是呈直线变化,比较复杂,总的变化趋势大体一致。 |
| 9. | As the balancing platform tends to make the barycenter move backward , a more balancing stress distribution under the wall , a higher and steadier wall can be achieved . furthermore , the resupine back of the downward wall not only works reasonably , but also can reduce the amount of excavation and filling obviously . so gravity retaining walls with balancing platform are applied heavily 衡重式挡土墙因具有衡重台使墙身重心后移、墙底应力趋于平衡,可提高挡土高度、增强墙体稳定性;且仰斜式下墙不仅受力合理、还可减少开挖与回填量等优点而被大量采用。 |
