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 to quan­ti­fy 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 com­pacts the se­di­ment (op­po­site to li­que­fac­tion which is the case when the shaking is more in­ten­se and ex­cess pore pres­su­re de­structs the se­di­men­t's fa­bric). By using ad­van­ced la­bo­ra­to­ry me­thods like cy­clic tri­a­xi­al tests, 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 ma­ter­i­als and their de­pend­ence on para­met­ers as well 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.
