摘要
云南省硕多岗河吊江岩水电站地理环境复杂,地质条件恶劣,在修建挡水建筑物之前需对其地基进行加固处理,以满足建筑物对地基的要求。本文针对该地基实际情况,采用有限元软件SIGMA/W对地下地基沉降进行变形分析和地基应力计算,对比相关规范手册,效验是否满足规范要求,为其地基处理方式的选择提供合理依据,可供实际工程参考。
The Diaojiangyan hydropower station of Yunnan province has a complex and adverse geographical environment. Its foundation must be reinforced before building the dam in order to meet the demand of foundation bearing capacity. Considering above these, in the paper, the foundation＇s sedimentary deformation was analyzed and the stress was calculated by the finite element software SIGMA/W. The conclusions which were compared with the standard values from specifications manual, can not only provide a reasonable basis for foundation treatment but be referred by practical project.
