1. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system
Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE

2. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas
Abstract : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. READ MORE

3. Ground Improvement by Dry Deep Mixing Lime-Cement Column Panels as Excavation Support
Abstract : Many urban areas near the coastal regions of Sweden are characterized by post-glacial clay deposits with very low undrained shear strength and high compressibility. Column type ground improvement by the Deep Mixing, DM, method using a binder mixture of lime and cement is commonly used in areas with poor soil conditions due to its cost-effectiveness, predominantly for settlement reduction and to improve the stability of embankments.

4. Deformation Behavior of Lime/Cement Column Stabilized Clay
Abstract : Deep stabilization of clay with lime/cement columns has lately become one of the most frequent methods for improvement of soft clays. The method is cost effective, as it results in a drastic reduction of settlement. The theories used for design were originally developed for lime columns. READ MORE

5. Long Term Settlements in Soft Clays
Abstract : When structures are founded on deep layers of lightly overconsolidated, soft clay large settlement often occur during a long period of time after completion of the structure. Therefore it is of major importance to be able to calculate and predict the expected settlements with a satisfactory degree of accuracy, as this has a great impact on the design of the foundation and the possible need for soil improvements.
