摘要
板间距大小是斜插式桩板墙结构关键设计参数,也是该结构能否被推广应用的核心问题.本文采用ABAQUS有限元软件分析了板间距变化对斜插式桩板墙板间竖向土拱效应的影响规律,给出了斜插式桩板墙的合理板间距范围,同时以相邻板板底作为拱脚支撑,计算得到了斜插式桩板墙板间竖向土拱拱轴线方程,并验证了受力分区的合理性.分析结果表明:斜插式桩板墙板间距大小与拱效应强度关系呈现为“S”型,合理的板间距取值范围为0.2~0.4倍板宽,且板间自然平衡拱的主应力合理拱轴线为椭圆曲线的一部分。
The distance between plates is the key design parameter of oblique inserted pile-sheet wall structure,and it is also the core problem of whether the structure can be popularized and applied.In this paper,the influence of the change of plate spacing on the vertical soil arch effect between oblique inserted pile-board wall is analyzed by using ABAQUS finite element software,and the reasonable plate spacing range of oblique inserted pile-board wall is given.At the same time,with the adjacent slab bottom as the arch foot support,the vertical soil arch axis equation between oblique inserted pile-board wall is calculated,and the rationality of force division is verified.The analysis results show that the relationship between the spacing of oblique inserted pile-board wall and the strength of arch effect is the shape of"S",and the reasonable range of plate spacing is 0.2 to 0.4 times the width of plate,and the reasonable arch axis of natural balance arch between plates is a part of elliptic curve.
