Settlement Characteristics and Prediction of Weak Expansive Soil Subgrade Based on Track Geometry Measurements
نویسندگان
چکیده
The weak expansive soil subgrade of the railway in operation is prone to settlement a high-temperature climate, which results rapid deterioration geometric dimensions track, and affecting safety train operation. This paper uses Track Geometry Measurements (TGM) analyze characteristics track geometry parameters soil. Also establishes Settlement Prediction Model (SPM) identify time predict value before maintenance. SPM applies mileage k285+000∼k300+000 weakly section Han-Dan Railway. It was verified by TGM 20 positions this section. show that has high application value.

Influence of Soil-industrial Effluents Interaction on Subgrade Strength of an Expansive Soil-a Comparative Study
The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a v...

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...
