PhD 3/3 Futureproof Tunnels: Monitor, explain and predict degradation in tunnels

Published Deadline Location
18 Jan 19 Feb Delft
Do you want to obtain a PhD while researching Future Proof Tunnels? Monitoring, explaining and predicting degradation?

Job description

The Faculty of Civil Engineering and Geosciences has started a research cooperation with Centrum Ondergronds Bouwen (COB), the Dutch Center for underground space technology and underground space use.

The Futureproof Tunnels research program looks into the challenges posed by aging underground infrastructure and the upcoming renovations of (mostly immersed) tunnels in soft soil conditions. 

The current standard in monitoring tunnels does not provide enough information to analyze the deformation and structural behavior of immersed tunnels. This stems in part from the assumption that deformation during operation would be limited to small-scale vertical deformations caused by settlements. However, the limited data available shows that tunnels undergo significant deformations in multiple directions, both vertically and horizontally resulting in local rotations. Accurate and continuous monitoring of tunnels is necessary to gain insights into the way tunnels deform and which external  factors play a role. This project takes on the challenge of monitoring the tunnel deformation and establishing all external load factors and detailed subsoil data.

In PhD project 3 the aims is to monitor, explain and predict degradation in tunnels. To this end, monitoring strategies and sensor technologies are being developed and will be applied in tunnels. Combining monitoring data with existing degradation models makes it possible to predict degradation and provide reliable risk forecasts. The focus of the research is on critical locations such as joints, transitions, splash zones, where concrete in combination with other materials is also exposed to more extreme loads and/or deformations.

You are expected to develop, test, select and install degradation monitoring systems in the tunnel, collect monitoring data and further develop damage models and constitutive description of mechanisms to predict the influence of multiple mechanisms.

Requirements

Applicants should possess a master’s degree in Civil Engineering or a related discipline. An aptitude for experimental testing and interpretation of data is essential. This includes an interest in the design and application of monitoring systems.

You are also expected to contribute to the monitoring program and data analysis; hence, a strong background in soil mechanics and/or structural mechanics is highly appreciated.

In this role it is expected that you cooperate closely with other members of the research team and with the COB expert committees that will guide the project in conjunction with the university supervisors.

Communication skills are important, and applicants should have a high level of proficiency in written and spoken Dutch and English.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.

Conditions of employment

Fixed-term contract: 18 months + 30 months.

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.
