Some improvement suggestions are made to the calculation of the bearing capacity of composite plastically-bearing-pile foundation with large pile distance and can be referential to similar foundations design.Keywords: composite pile foundation;nplastically-bearing-pile foundation;nsafety degree；bored pile作者簡介：陳火忠，學(xué)士，高級工程師，一級注冊結(jié)構(gòu)工程師，Email：chz1801@163.com。
