| 1. | The problems in the planning of journals sponsored by the institutions of higher learning and the solutions 岩层中抗拔桩的承载力计算方法探讨 |
| 2. | The bearing capacity and settlement property of single pile under axial load is an important subject in pile foundation theory research 单桩的承载力与沉降特性是桩基理论研究中的重要课题。 |
| 3. | Determining and improving the bearing capacity of steel tubular piles for piled wharfs has long been an issue that the engineering field has endeavored to study and solve 摘要确定和提高高桩码头钢管桩的承载力是工程界一直致力于研究的问题。 |
| 4. | Moreover , the experimental formula of the hearing capacity of the new type of pile is discussed and presented , it will be a theoretic reference to use this new type of pile in engineering 此外,对挤扩支盘桩的承载力公式进行讨论并提出建议,对该新型桩在工程上的应用提供了理论依据和参考。 |
| 5. | Using prediction can give the most technical economic effect , providing design with reasonable data of pile ' s bearing capacity , bringing into play pile ' s bearing capacity completely , thus can save the engineering cost 采用预测法所带来最大的技术经济效益还在于可以及时地给设计提供合理的桩承载力数值,充分利用桩的承载力,节约工程造价。 |
| 6. | Through the algorithm of ann , the author has made out the three - layers and four - layers bp nets to intelligently study and reason , supporting decision on the detail reasoning , such as piles " capacity and pile cap ' s bearing pressure 根据神经网络的学习算法,编制了三层及四层bp网络的学习及推理程序。该程序在某些细部问题(如确定桩的承载力、承台反力等)上提供辅助决策。 |
| 7. | It ' s 70 years " last century that began to test study in our country , today we have mastered some working ways . more and more pile foundations of high buildings use later pressure grouting technology to improve the pile ' s bear ability from 80 years " last century 我国从上世纪80年代开始,越来越多的高层建筑的桩基础应用后压浆工艺来提高桩的承载力,其施工工艺及计算方法也得到不断的提高。 |
| 8. | Under the vertical load , the vertical pile group has bigger bearing capacity than the battered pile group . under lateral load , the positive battered pile group has bigger bearing capacity than the vertical and negative battered pile group . both model experiments and prototype experiments are conducted 与单桩类似,竖向受荷直桩群桩承载力比斜桩群桩大;水平受荷群桩, “正斜”单桩组成的群桩比直桩群桩和“负斜”单桩组成的群桩的承载力大。 |
| 9. | The drilling hole pour pile technique has been wide - ranging used in the high buildings " foundation and base of the wide span construction and base of bearing weighty load construction , but the geology conditions that surrounding the pile are differ in thousands of ways , extraordinary , the soil there is small opening and it can be compressed and the bottom of the pile ' s hole there is much more dregs , so many confuse reasons ca n ' t be computed weaken the pile ' s ability of bear load 钻孔灌注桩施工技术在高层建筑、大跨度、大承载力的基础工程中得到了广泛的应用,但是,地层土壤存在孔隙、土壤具有可压缩性、孔底存在沉渣等许多不可明确计算的因素,使桩的承载力存在不同程度的削弱,实际承载力与设计值有较大出入。 |
| 10. | The model experiments results indicate that the pile group composed of extending all around piles can bear inclined load better . this is beneficial to the foundation of transmission tower . the prototype experiments results indicate that the micropile ' s load capacity is satisfied with design 模型试验发现,伸向四周的单桩组成的群桩具有更好的抵抗倾斜荷载的能力,这一点特别有利于输电线路基础等;原型试验发现,微型桩单桩和群桩的承载力完全达到设计承载要求,其群桩效率在0 . 9左右。 |
