PhD Project

My pro­ject is fun­ded by the Eu­ro­pean Com­mis­si­on, pro­ject SLATE (Sub­ma­ri­ne lands­li­des and their im­pact on Eu­ro­pean con­ti­nen­tal mar­gins). To­pic: Quantitative Geotechnical Characterization of Seismic Strengthening Effect on Subaquatic Slope Stability

This project consists of a laboratory based, generic study that aims at quantifying the strengthening effect of earthquake loading on marine slope sediment deposits. The seis­mic streng­the­ning pro­cess in­vol­ves gra­du­al den­si­fi­ca­ti­on of se­di­ment cau­sed by re­pea­ted ear­t­h­qua­ke events that de­wa­ter the se­di­ment (also cal­led: dy­na­mic com­pac­tion, as op­po­sed to li­que­fac­tion in case the shaking is more in­ten­se so that ex­cess pore pres­su­re de­structs the se­di­ment fa­bric and bon­d­ing forces bet­ween par­ti­cles). By using a dy­na­mic tri­a­xi­al sys­tem at the MARUM with fre­quen­cies up to 50 Hz, the in­crea­se in un­d­rai­ned she­ar strength as a func­tion of dy­na­mic loa­ding and pore wa­ter drai­na­ge can be mea­su­red, which sheds light on the sta­bi­li­ty of the stu­di­ed slo­pe as a re­sult. The main goal is to explore the nature and significance of seismic strengthening in sediments of different mineralogical and grain size compositions. Expected scientific outcome is to enhance our understanding of:

  • Seismic strengthening of granular material and its dependence on parameters such as the seismic intensity, number of seismic events and overburden stresses.
  • Seismic strengthening of geotechnically more complex types of soils, for example silts, clays, sand-silt-clay mixtures, tephra, and diatom ooze.
  • Case study on natural samples incorporating real earthquake signals.
