Eemdijk full-scale test on dike reinforced by sheet pile

Dikes in the Netherlands have traditionally been constructed with soil. Climate change and subsidence requires heightening and or reinforcing these existing dikes. Traditional reinforcements demand additional space, which in some cases conflicts with existing buildings. Applying sheet pile walls in dikes allows for strengthening while minimizing the increase in footprint. However, a validated design approach that complies with relevant regulations lacks. To enable the validation of a proposed design approach, a full-scale field test programme (Eemdijkproef) was performed near the town of Eemdijk, The Netherlands. It consisted of a step wise approach: 1) sheet pile pullover tests, 2) ground dike stability test, 3) sheet pile dike stability test. All tests were loaded until failure occurred. The two similar test dikes were constructed at full scale (5m high, 25m wide, 60m long). In one dike an 18m long sheet pile wall was installed. This paper presents the test setup, monitoring, measurements and first findings. The test program provides better insight in the soil-structure interaction of the reinforced dike, on soft soil, under high water and uplift conditions. Ultimately this will lead to a validated design approach for sheet pile walls in dikes.<br><br>This repository contains the Eemdijk full-scale test raw data, scripts, processed data, informative documents, photos and videos.

荷兰堤防传统上采用土体填筑施工。气候变化与地面沉降要求对现有堤防进行加高或加固。传统加固方案需额外占用土地，部分场景下会与既有建筑产生空间冲突。在堤防结构中采用板桩墙（sheet pile walls）可在实现加固目标的同时，最大限度缩小占地增幅。然而，当前仍缺乏符合相关规范的经验证设计方法。为验证所提出的设计思路，研究团队在荷兰埃姆迪克（Eemdijk）镇附近开展了全尺寸现场试验项目（Eemdijkproef）。该试验采用分步实施流程：1）板桩拉拔试验（sheet pile pullover tests），2）堤防整体稳定性试验（ground dike stability test），3）板桩加固堤防稳定性试验（sheet pile dike stability test）。所有试验均加载至结构破坏。两座相似的试验堤防均为全尺寸建造（高5m、宽25m、长60m），其中一座堤防内安装了18m长的板桩墙。本文介绍了试验装置、监测方案、测量工作与初步研究结果。该试验项目可深化对软土地基上加固堤防在高水位与扬压条件下的土-结构相互作用机制的认识，最终将催生一套经验证的堤防板桩墙设计方法。<br><br>本仓库包含埃姆迪克全尺寸试验的原始数据、脚本、处理后数据、参考资料、照片与视频。本数据集体量约50GB。<br>"PO-test"、"GD-test"、"SPD-test"及"POVM Eemdijk"压缩包完整代表了POVM研究团队（Deltares / Witteveen+Bos）在2019年埃姆迪克试验开展前、期间与赛后所使用的POVM项目数据集。详见"011 readme.."文档。<br><br>"PhD analysis Eemdijk 2022.zip"直接关联2022年博士论文中报告的埃姆迪克试验分析内容：《有机土地基上板桩加固堤防的试验与建模：来自埃姆迪克全尺寸破坏试验的启示》（TESTING AND MODELING OF SHEET PILE REINFORCED DIKES ON ORGANIC SOILS; INSIGHTS FROM THE EEMDIJK FULL-SCALE FAILURE TEST），作者Arny Lengkeek（2022年）。详见"021 Readme.."文档。
