Examples
- Measures to ensure quality of grouting pile head
灌注桩桩头质量保证措施 - In order to have more load capacity in drilling pile , size of drilling holes may be increased , or enlarged the end of pile by explosion , or driving the cast - in - place pile twice
为了提高钻孔桩承载能力,可在钻孔时孔头扩大,也可以采用爆破法使桩头扩大,现浇混凝土桩二次复打也可提高承载能力 - 4 ) the dynamic interaction factors of pile groups under horizontal earthquake actions and dynamic forces considering axial loads are first derived in this field , and the affection degree of the factors by the axial loads are investigated
4 )首次推导了考虑轴向力时水平地震作用下和桩头动力作用下群桩动力相互作用因子，分析了轴向力对动力相互作用因子的影响程度。 - During the low strain dynamic test of the foundation pile , the adoption of the velocity sensor to the direct measurement of the relative displacement of the pile head is helpful to reducing the improper dependence upon the measured intrinsic frequency valuesof the pile soil system in calculating vertical bearing capacity of the single pile , and is hence conducive to raising the accuracy of the calculated vertical bearing capacity of the single pile
基桩低应变动测中，采用速度传感器直接测出桩头的相对位移，在推算单桩竖向承载力时，有助于降低对桩土体系固有频率测定值的过分依赖，从而有利于提高单桩竖向承载力推算值的准确程度。 - 3 ) the single pile horizontal dynamic impedance function in visco - elastic ground considering axial loads is first derived in this field , and the parameter analysis shows that the variation of single pile horizontal dynamic impedance cannot be neglected when considering the axial loads , and it ' s appropriate to considering the axial loads when calculate the single pile horizontal dynamic impedance
3 )首次推导了粘弹性地基中考虑桩头轴向力时单桩的水平动力阻抗函数，通过参数分析发现，轴向力对单桩动力阻抗刚度存在不可忽略的影响，当轴力较大时，计算单桩的动力阻抗以考虑轴力为宜。
