在工业建设中,某些构筑物的基础要承受斜向荷载。例如矿山井架的斜腿基础,拱脚基础等,主要承受由斜腿和拱脚传来的斜向荷载N。以往一般都设计成平底形式的基础如图1。 In industrial construction, the foundations of certain structures are subject to diagonal loads. For example, the slanted leg foundation and the arched foot foundation of a mine derrick mainly bear the diagonal load N transmitted from the slant legs and arch feet. In the past, the basic design of a flat base was generally as shown in Figure 1.
