Polymer optical fiber (POF) sensors have the unique ability to measure high strain distributed along the fiber up to 40% using the optical time-domain reflectometry (OTDR) technique. Both, standard PMMA fibers and perfluorinated (PF) graded-index (GI

Two phenomena characterize cyclic axial loaded piles: accumulation of plastic pile displacements and degradation of pile capacity with increasing load cycles. The reason for this complex pile-soil-interaction is still not well understood. Hence, load

Fiber optic sensors based on polymer optical fibers (POF) have the advantage of being very elastic and robust at the same time. Unlike silica fibers, standard PMMA POF fibers can be strained to more than 40% while fully maintaining their light guidin

The book reviews recent developments and research results on excavations and foundations found in and on soft soil deposits. It gives an overview of the material properties of soft soils and offers new foundation improvement techniques in road and ra
