Geotechnical Problems Of The Foundation Of Road Embankments By The Bridge Structures

Abstract

This work presents the geotechnical problems occurring in the interaction area between road embankments and the bridge structures in case a subsoil characterised by complex and complicated geological and engineering conditions. These significant problems that occur during the design, performance and exploitation of the abutment structures, are illustrated on the example of engineering practice in Lower Silesia, concerning a road embankment that constitutes access to the bridge. The results of numerical analyses concerning the process of consolidation of low-strength soils and their impact on the settlements of road embankment indicate the need to carry out such analyses also in the cases, when the soft soils occur in the direct geotechnical layer under the designed embankment. The Authors included in this article a discussion regarding other effective actions and solutions that can be used in the design and performance phase, leading to the elimination or reduction of problems concerning the connection of engineering structures with road embankments, which have been recurring for years, ultimately resulting in the improvement of quality, comfort and safety of road exploitation.

Penerapan Metode GPR dan Geoteknik pada Kajian Jalan, Jembatan, dan Lereng : Review

“…Analisis numerik proses konsolidasi tanah kekuatan rendah dan dampaknya terhadap penurunan tanggul jalan dilakukan oleh Batog & Stilger-Szydło (2019) untuk mendapatkan solusi yang efektif dalam tahap desain dan kinerja yang mengarah pada meminimalkan masalah terkait sambungan struktur tanggul dalam rangka meningkatkan mutu dan keselamatan pengguna jembatan. Dalam metode tersebut, uji investigasi lapisan bawah tanah dan analisis varian dari proses konsolidasi digunakan untuk menjelaskan penyebab penurunan struktur.…”

“…Dalam metode tersebut, uji investigasi lapisan bawah tanah dan analisis varian dari proses konsolidasi digunakan untuk menjelaskan penyebab penurunan struktur. Dengan mempertimbangkan hasil uji verifikasi serta nilai parameter geoteknik yang ditentukan di laboratorium, diperoleh nilai ukuran total tiang, laju konsolidasi dan prediksi penurunan (Batog & Stilger-Szydło, 2019).…”
