摘　　要：首先从试验和理论2个方面确定了山区变电站高填方地基工后沉降的主要影响因素,即填方高度和变形模量,并给出计算地基工后沉降的初步公式;然后结合2个典型工程对公式中的系数进行修正,拟合出一个实用的经验公式;最后以2个山区变电站工程为例进行分析,发现理论计算值与实测值吻合良好,有力地论证了该公式的有效性。所得的结论为山区变电站高填方地基工后沉降的进一步研究和相关规范的制定提供了参考。Firstly,authors presented the main influencing factors of post-construction settlement of transformation substation high fill foundation in two ways of experiment and theory, which is fill height and deformation modulus,and a primary formula of post-construction settlement of foundation was given.Then,the key coefficients of post-construction settlement were modified and a useful formula was deduced based on two typical transformation substation projects.At last,taking two transformation substation projects as an example,the theoretical computing values agreed well with the measured values,which showed the validity of the formula.This paper is useful for the further research of post-construction settlement of transformation substation high fill foundation in mountainous areas and designing of relevant codes.
