Verification of sufficient anchor lengths with the FEM for double back anchoring and fixed earth support

The article examines whether the verification of the minimum length of grouted anchors for the support of excavation walls using the finite element method (FEM) also leads to plausible results if the wall has an additional fixed earth support. This is intended to show that the associated verification of the required anchor length can not only be carried out using the established “verification of stability in the lower failure plane”, but also with strength reduction method following an FEM calculation, as will be made generally possible in the foreseeable future by the Europe-wide standardization of Eurocode 7. The verification against failure of the earth support is also included in the considerations. Determining the failure mechanisms in the subsoil is of particular importance here. One question is whether a variation of both anchor lengths and the earth support results in different failure mechanisms, as they are specified in the classic methods. It will also be shown how the stability calculated with the FEM develops over the construction phases. From this, knowledge can be gained about the special role of the mode of the wall's earth support and aspects for the optimization of such a construction.

用有限元法验证双后锚和固定土支护的足够锚杆长度本文探讨了用有限元法（FEM）验证开挖墙的最小注浆锚杆长度是否也能得出合理的结果，如果墙有额外的固定土支护。这是为了表明，所需锚固长度的相关验证不仅可以使用既定的“下破坏面稳定性验证”进行，还可以使用FEM计算后的强度折减方法进行，这将在可预见的未来通过欧洲规范7的欧洲范围标准化普遍可行。对接地支架失效的验证也包括在考虑范围内。确定底土的破坏机制在这里尤为重要。一个问题是锚杆长度和土支撑的变化是否会导致不同的破坏机制，正如经典方法中所规定的那样。还将显示用有限元法计算的稳定性在施工阶段是如何发展的。由此，可以了解墙体土支撑方式的特殊作用，以及这种结构的优化方面。

Design of protection works for torrent control

The design and construction of protective structures for torrent control is an interdisciplinary task. The effects are derived from the naturally influenced runoff processes in the streams. Structural engineering (mostly solid construction) and geotechnical aspects must be taken into account in the design and construction of these structures. In order to standardise the traditional procedures in this field and make them compatible with the Eurocode concept, ÖNORM B 4800 Protective structures for torrent control [1] was published by the Austrian Standards Institute in April 2025, based on the four-part ONR 24800 series. This standard regulates the procedure for the design, construction, dimensioning and maintenance of protective structures for torrent control. This article aims to present the essential aspects of the dimensioning and construction of torrent barriers based on this standard, as well as new scientific findings on the effects on protective structures. A sufficiently robust structure results from an optimal design, structural/geotechnical design in accordance with relevant structural engineering standards and a suitable structural design of the components. In addition to these aspects, the determination of the effects on proven and tested models, particularly taking into account changing conditions due to climate change, is of particular importance.

防汛防护工程设计防汛防护工程的设计与施工是一门交叉学科。这些影响来自于溪流中受自然影响的径流过程。结构工程（主要是固体建筑）和岩土方面必须考虑到这些结构的设计和施工。为了使这一领域的传统程序标准化，并使其与欧洲代码概念兼容，ÖNORM B 4800洪流控制防护结构[1]由奥地利标准研究所于2025年4月出版，基于四部分ONR 24800系列。本标准规定了激流控制防护结构的设计、建造、尺寸和维护程序。本文旨在介绍基于该标准的激流屏障的尺寸和施工的基本方面，以及对防护结构影响的新的科学发现。一个足够坚固的结构是根据相关结构工程标准进行优化设计、结构/岩土设计和适当的构件结构设计的结果。除了这些方面之外，确定对经过验证和检验的模式的影响，特别是考虑到气候变化造成的条件变化，是特别重要的。
