part time professor in the Master in Structural Engineering program:lectures: geotechnical engineering, settlement risk management, foundations and soil-structure interaction

Professor of Structural Civil Engineering since 2008 at the Construction Management and Engineering (CME) group of the CTW Faculty of the University of Twente. In this capacity, I was mainly involved in lecturing the introduction to civil engineering in the bachelor course and more structural engineering topics in the master courses. Research: involvement in a number of PhD studies.

Vanaf 2005 tot 2011 : hoogleraar Civiele Techniek verbonden geweest aan aan de Faculteit Militaire Wetenschappen (FMW, onderdeel van de Nederlandse Defensie Academie (NLDA). De FMW verzorgt samen met de Koninklijke Militaire Academie (KMA) de officiersopleidingen van de Krijgsmacht. Taken : onderwijs en onderzoek op het gebied van de (militaire) civiele techniek (military engineering).

The aim of this research was to examine the use of grouting methods for pile foundation improvement, a generic term that is used here to define both foundation renovation (increasing the bearing capacity of a pile foundation that has insufficient bearing capacity) and foundation protection (safeguarding the piles of the foundation against possible damage resulting from underground construction activities in the vicinity).

A full-scale test, of which the general set-up and consistency check are outlined in the thesis, examining the feasibility of foundation improvement by means of grouting techniques was conducted in Amsterdam. The main part of the thesis focuses on permeation grouting, jet grouting and compaction grouting. For each method, first some more general aspects like history, grouting equipment, grouting parameters and fields of application are outlined. Subsequently existing theories used in modelling the grouting process are examined and compared. The test results are discussed. By using the pile displacements, soil stresses, pore pressures and pile bearing capacity measured in the test, it was possible to examine the influence of grouting methods on pile foundations. The use of and suitability of geophysical verification methods for grouting, which were necessary to determine the shape and position of grouted elements, were also considered. To determine how grouting methods can best be applied for foundation renovation purposes, the cost of grouting methods and the hindrance that they cause have been compared with those of conventional foundation renovation methods.http://repository.tudelft.nl/assets/uuid:7a5f60e9-36d2-4311-beda-881972d6ab10/ceg_stoel_20010911.pdf Show less
