摘要
桶形基础是近年开发的一种新型的可广泛应用于海洋工程结构的基础形式。由于多种优越性而受到各国石油部门的重视,并引起许多研究人员的关注。通过在饱和砂中的单桶和四桶基础模型实验,研究了桶形基础的静承载特性。分别进行了垂直方向和水平方向的加载实验,其中,四桶基础水平方向加载又分为沿四桶中心构成的正方形的平行边方向和对角线方向施加,得到了载荷位移曲线,对单桶和四桶基础承载力特性,以及加载方向和速率的影响进行了分析和比较。
Bucket foundation is a new type of foundation which may be used extensively in offshore structures. It is attracted by oil corporations and researchers because of its several advantages. The static bearing capacity of bucket foundation is studied by experiments of single-and four-bucket foundation in saturated sand layer. The characteristics of bearing capacity under vertical load and horizontal load are obtained experimentally. The horizontal load of four-bucket is applied in the direction parallel to one sideline or one catercorner of the quadrangle formed by the centers of four buckets. The load-displacement curves are obtained. The characteristics of single-bucket and four-bucket foundation, the effects of load direction and load rate are analyzed.
