某建筑物地基基础设计等级为乙级，其柱下桩基采用预应力高强度混凝土管桩(PHC桩)，桩外径为400mm，壁厚95mm，桩尖为敞口形式。有关地基各土层分布情况、地下水位、桩端极限端阻力标准值q_pk桩侧极限侧阻力标准值q_sk及桩的布置、柱及承台尺寸等，如图所示。

该建筑工程的抗震设防烈度为7度，设计地震分组为第一组，设计基本地震加速度值为0.15g。细中砂层土初步判别认为需要进一步进行液化判别，土层厚度中心A点的标准贯入锤击数实测值N为6。试问，当考虑地震作用，按《建筑桩基技术规范》（JGJ94—2008）计算桩的竖向承载力特征值时，细中砂层土的液化影响折减系数ψ₁，应取下列何项数值（）.
提示：按《建筑抗震设计规范》（GB50011—2010）解答。

A．0

B．1/3
