摘　　要： 本文通过在软土地区对钢筋笼内预埋钢筋计的灌注桩进行水平静载试验,来对桩基在水平荷载作用下的受力性状进行研究。结果表明,灌注桩的弯矩、剪力和桩侧土土抗力主要集中在桩顶下20米深度范围内;灌注桩的大弯矩点处桩身剪力值为零,桩身剪力最大值处桩侧土土抗力为零;灌注桩的大弯矩点发生在桩顶下6米左右和15~17米深度处,在本工程的工程桩设计中应着重考虑。 In this paper, the horizontal static load test was conducted on the bored piles with pre-buried steel bar meter in the steel reinforcement cages. In the test, the force character of pile foundation under horizontal load was studied. The test results showed that, the bending moment, the shear force and the soil resistance of the bored piles was mainly concentrated in the depth of 20 meters above the top of the pile; the bending moment was largest when the shear foce was zero, while the shear force was largest when the soil resistance was zero; the maximum moment of the bored piles lay in the depth of 6meters and 15 to 17 meters, which should be considered in the design of the engineering piles.
