The problem of stabilization of landslides in glaciotectonically disturbed areas. Case study: road engineering structure

Abstract

The process of the construction of engineering structures situated within glacitectonically disturbed areas cause the necessity to link engineering operation with knowledge of geological processes. One of the examples of such a structure was the construction of the west bypass of Zielona Góra. The roadworks were connected with the necessity of deep excavations into glacitectonically disturbed soil structures. This caused intense changes in the soil mass and - as a consequence - loss of slope stability and the construction of landslides. At the construction stage numerous landslides were already active, which additionally increased during intensive road use. In spite of technical stabilization, there was a risk of loss of slope stability, which is a consequence of stresses in soil mass and engineering activity. This article presents the results of the monitoring of the slope stability during intensive road exploitation.
