| 1. | Applicaton of punched broken rock pillars under mud soft ground base condition in feicheng mineral area 肥城矿区淤泥质软弱地基条件下振冲碎石桩的应用 |
| 2. | Pile foundation is widely applied in many kinds of ground and under different type of loading 桩基础能较好地适应各种地基条件和各种荷载情况,是我国工程建设中广泛采用的基础形式。 |
| 3. | Considered the complexity of geological structure , how to study the interaction of intake tower and slope is important both in theoretical research and engineering 如何研究在复杂地基条件下进水塔与边坡的相互作用具有重要的理论意义和工程应用价值。 |
| 4. | To improve the bearing capacity in varying ground conditions , soft spots are usually filled with consolidated hardcore or a weak concrete , before the foundation is laid 为了在不同的地基条件下提高基础的承载力,在浇注基础前,通常用碎石垫层加固或用强度低的混凝土来填充土质松软的地方。 |
| 5. | With the help of marc program , the author , through simulating the different foundation condition , analyzes the changed rule of stress and displacement , discusses the active mechanic of the flexible approach slab in dealing with the jump 文中运用marc软件,通过模拟不同的地基条件,分析应力和位移的变化规律,研究了楔型柔性搭板在处治桥头跳车中的作用性状。 |
| 6. | Because of the diversity and complexity of structure form and ground condition , characteristic the research of reciprocity of structure - boxbase - ground has very outstanding importance in various beared terms of stress and distortion 由于结构形式及地基条件的多样性和复杂性,上部结构、地基、基础相互之间在各种受荷条件下的应力、变形特性的研究有其突出的重要性。 |
| 7. | The effect of complex groundsill and dam body ' s construction process can be considered conveniently when finite element method is used to analyze dam body ' s stress . but there is no design criterion correspondingly because of the stress concentration that is caused by load at dam heel and dam toe under elastic state . furthermore , its value is easily affected by mesh size 有限元法分析拱坝坝体应力可以较方便地考虑复杂地基条件和坝体施工过程的影响,但是由于弹性状态下拱坝坝踵、坝趾处受荷载后的应力集中现象,而且其数值受网格尺寸影响较大,因此至今无与之相应的设计准则。 |
| 8. | It is stated clearly by researching , the cast - in - place pile must be constructed according to strict technological process on condition that pebble geological structure , and more important that the drilling technology and the reasonable property index of mud are chose correctly on the basis of the condition of pebble geological structure 研究表明,江汉平原地区卵石地基条件下,钻孔灌注桩必须要按严格的工艺流程施工,最重要的是根据卵石地基的地质情况,正确选择钻孔工艺和合理的泥浆性能指标。 |
| 9. | This type was adopted for the first time in cangzhou city and hebei province , and it is suitable for the region with poor foundation , it offers wide condition for the construction and it is economical , its exterior is handsome , especially suits for the bridge of city . this paper is of great importance for guiding the design and calculation for this type of bridge ; and it promates the research and application of the new type of cfst for the purpose of widely spreading it in the field even the resign 下承式钢管混凝土系杆拱桥型式在沧州市乃至河北省都是首次采用,适于建于地基条件较差的地区,施工条件宽松,造价较经济,外型美观,尤其适用于城市桥梁。本文对今后该类型桥梁的设计计算和施工具有重要的指导意义,为在本行业乃至本地区继续推广钢管混凝土这一新型结构的研究与应用起到了推动作用。 |
