Steel sheet piles are used in geotechnics for retaining and quay wall constructions amongst others. The design of such sheet piles is based on structural analysis for construction and operational states. Manufacturing caused impacts due to pressing, vibratory pile driving and pile driving are not considered. Especially at highly loaded combined sheet pile walls of modern quay wall constructions often failures of sheet pile interlocking occur. Examples are Maasvlakte I at Rotterdam, Neue Kaiserschleuse at Bremerhaven and the JadeWeserPort (JWP) at Wilhelmshaven. In the framework of the proposed project the total loading of sheet piles are studied including impacts due to installation processes based on theoretical and numerical investigations. This includes investigations of the role of pile driving guide, of heat generation due to pile driving, and of spatial distribution of earth and water pressure acting on sheet pile walls. Main objectives of the project are design rules to reduce interlocking problems in future constructions.

钢板桩用于岩土工程中的挡土和码头墙建设等。这种板桩的设计是基于施工和运营状态的结构分析。不考虑因挤压、振动打桩和打桩造成的制造影响。特别是在现代码头结构的高荷载组合板桩墙中，板桩互锁失效时有发生。例如鹿特丹的Maasvlakte I、不来梅港的Neue Kaiserschleuse和威廉港的JadeWeserPort（JWP）。在拟建项目的框架内，对板桩的总荷载进行了研究，包括基于理论和数值研究的安装过程所产生的影响。这包括调查打桩指南的作用，由于打桩产生的热量，以及作用在板桩墙上的土压力和水压力的空间分布。该项目的主要目标是设计规则，以减少未来施工中的联锁问题。
