摘　　要：通过使用静力触探方法统计了整个太原理工大学明向校区场地土的桩侧摩阻力和桩端阻力的变异情况,从而用可靠度方法提出了针对太原理工大学明向区场地土的桩侧桩端的抗力分项系数。最后用太原理工大学明向区图书馆主楼的灌注桩的载荷试验来验证了由本文提出的桩的抗力分项系数的合理性,证明单桩承载力设计值与试桩确定的单桩承载力特征值符合性较好,这样为区域性场地土中桩基抗力分项系数的确定提供了参考。This paper counts the variation of the pile＇ s side friction and end resistance on theMingxiang campuses site soil of TYUT by using CPT, and put forward the resistant coefficientsof the side friction and end resistance for Mingxiang campus＇s site soil of TYUT by using reliabil-ity method. At last, the paper tests and verifies that the single pile load-carring capacity canmatch the characteristic value of the vertical load-carring capacity of the single pile determined bythe load test, which provides some reference about the resistant coefficients on the regional sitesoil.
