This sixth manual in our GEO5 engineering series delves into the advanced design and analysis of anchored retaining walls. Using GEO5 software, this guide offers a step-by-step approach to designing a retaining wall with multiple rows of anchors, focusing on ensuring stability and safety under complex loading conditions. Now available for download, this manual is a crucial resource for geotechnical engineers aiming to master the intricacies of anchored wall design.
Learning Objective:
The goal of this manual is to provide users with the expertise required to design a multi-anchored retaining wall using the EN 1997-1 (EC 7-1, DA3) standard. Users will learn how to perform detailed stability analyses, verify cross-sections, and optimize the design to withstand various loading scenarios, including seismic forces.
Assignment Description:
In this assignment, users are tasked with designing a retaining wall with multiple rows of anchors, using a complex geological profile and considering both permanent and variable loads. The manual guides users through the process of setting up the wall geometry, defining soil profiles, selecting appropriate materials, and performing comprehensive stability checks using GEO5. Special emphasis is placed on analyzing the wall’s behavior under seismic conditions and optimizing anchor placement.
Outcome:
By completing this assignment, users will be capable of designing and analyzing complex anchored retaining walls that meet stringent safety and performance standards. They will gain practical experience in using advanced features of GEO5 to handle challenging geotechnical conditions and ensure the reliability of their designs.
Conclusions:
The manual concludes that the designed anchored retaining wall, after undergoing thorough analysis and optimization, is suitable for the intended application. The structure, supported by multiple rows of anchors and verified under both static and seismic conditions, demonstrates satisfactory stability and safety. The final design, with optimized anchor forces and embedment depths, provides a robust solution for complex geotechnical scenarios.
