摘要
为了提高风电塔架基础的承载特性,提出了一种新型吸力基础型式——裙式吸力基础。采用ABAQUS有限元数值软件,对传统吸力基础和裙式吸力基础的竖向承载力特性进行了分析比较,得到了荷载-沉降关系曲线、周围土体隆起量及顶板底部土压力分布特性等。结果显示,由于"裙"的设置,裙式吸力基础相比于传统吸力基础其竖向承载力得到了有效的提高,且裙的引入分担了顶板受到的土抗力。
In order to improve bearing characteristics of the wind power tower foundation, a new type of suction caisson, called the skirted suction caisson, was pro- posed. With the finite element numerical analysis software ABAQUS, the vertical bear- ing capacity characteristics of traditional suction foundation and skirted suction cais- son were analyzed and compared, and the load-settlement relation curve, the upheaval value of surrounding soils and the earth pressure distribution under the top plate were obtained. The results show that, with the application of skirt structure, the vertical bearing capacity of skirted suction foundation improves effectively compared with that of traditional suction caisson, and the introduction of ＂skirt＂ shares part of earth pres- sure from top plate.
