摘　　要：对万州体育中心工程的3根机械冲孔灌注桩进行单桩水平静载试验,在桩身强度和水平位移两种控制工况下,确定其单桩水平承载力特征值、水平极限承载力,并推定地基土抗力系数的比例系数m值。试验结果验证了特殊地质条件下的桩基施工工艺,给出了桩基水平承载力与位移的计算参数,并为类似桩基工程的设计与施工提供了基础试验数据。Single pile horizontal static load tests were conducted on three mechanically punched cast-in-place piles of the Wanzhou Sports Center project,under the two control conditions of pile strength and horizontal displacement,determine the characteristic value of the horizontal bearing capacity of a single pile,the horizontal ultimate bearing capacity,and estimate the proportional coefficient m value of the foundation soil resistance coefficient.The test results verified the construction process of pile foundations under special geological conditions,provided calculation parameters for the horizontal bearing capacity and displacement of pile foundations,and provided basic test data for the design and construction of similar pile foundation projects.
