| 摘 要： | 桩在水平荷载作用下的受力性状是一个复杂的桩土相互作用过程。本文结合工程实例,通过现场水平静载试验,实测得到了水平荷载作用下大直径嵌岩灌注桩桩土共同作用时的工作性状,分析了桩体水平力、位移与时程关系、水平力与位移梯度关系、临界承载力以及地基土的水平抗力比例系数。试验结果可为今后同类桩的设计与研究提供参考。建议采用位移控制设计桩基础。 |

| Abstract: | The behavior of pile under horizontal load is a very complex process of pile-soil interaction.The behavior of large-diameter rock-socketed filling piles under horizontal load in pile and soil interaction is surveyed by field test.The relationships of horizontal load-time-horizontal displacement(H_0-t-X_0) and horizontal load-displacement gradient(H_0-(X_0/H_0),the critical bearing capacity and horizontal modulus of subgrade reaction(m) are analyzed.These test results are useful for the practical engineering and analysis of the same piles. |
| Keywords: | large-diameter and rock-socketed filling piles horizontal load interaction testing study |
