Abstract

Steel sheet piles are known for their straightforward assembly and construction, making them a popular choice that is often repurposed for other building projects once disassembled. Regarding the re-use of these steel sheet piles, understanding their behavior during penetration into the soil becomes pivotal. This study focuses on assessing the potential reusability of steel sheet piles as they penetrate into the soil. A laboratory-scale experiment involving the insertion of a steel sheet pile into a sand-filled tank was conducted. The experimental variables were the relative density of the soil, length of the steel sheet pile, and penetration method. The behavior of the sheet pile was analyzed, including the force-insertion length relationship and the strain of deformation occurring locally in the sheet pile. The results indicated that higher relative soil densities led to increased strain within the sheet pile. The strain values remained within the elastic range during the experiment. Notably, when interpenetrating the steel pile with a coupling mating joint test specimen, the strain showed an inverted mountain-shaped distribution within the interlock.

U型型钢桩压入性能试验研究

摘要

钢板桩以其简单的组装和施工而闻名，使其成为一种流行的选择，一旦拆卸，通常会重新用于其他建筑项目。对于这些钢板桩的再利用，了解它们在渗透到土壤中的行为变得至关重要。本研究的重点是评估钢板桩渗入土壤时的潜在可重复使用性。进行了一项实验室规模的实验，涉及将钢板桩插入充沙罐中。实验变量为土的相对密度、钢板桩的长度和贯入方法。分析了板桩的性能，包括力-插入长度关系以及板桩局部发生的变形应变。结果表明，较高的相对土壤密度导致板桩内应变增加。实验期间应变值保持在弹性范围内。值得注意的是，当钢桩与联轴器配合接头试验样本互穿时，应变在互锁内呈现倒山形分布。
