Özet (Çeviri)

It is planned to reopen Midsomer Norton Railway Station, which is a station on the Somerset & Dorset Heritage Railway Line, to traffic. As a first step, Midsomer Norton will be terminal and it is proposed to build a siding and a depot for the terminating trains. However, a ground investigation is essential before starting building the siding and the depot, as it is the vital part of any civil engineering process. Ground's behaviour must be known in order to form a structure on it. Data from ground investigation is a reference for any kind of structures. This study covers a site investigation including a desk study, walkover survey, sampling and laboratory testing in order to perform a suitable design. Moisture content test, liquid limit and plastic limit tests, standard compaction test, shear vane test and triaxial compression tests were carried out to determine the soil characteristics and to analyse the soil behaviour. 4 trial pits were excavated to depth of 0.8 metres, layers and visual properties of the soil were identified on site. The material is identified as mudstone of Mercia Mudstone Group, which is commonly encountered in constructions in the UK. Natural moisture content of the soil was obtained from moisture content tests applied on 8 samples, ranges from 27.98% to 40.57% depending on the location of the samples. Similarly, Atterberg Limits tests were performed on 8 samples and liquid limit was found between 63.66% and 90.13%, and plastic limit is between 37.92% and 54.67%. On the basis of these values, the soil material is defined as very high plasticity clay. After classification, compaction and shear strength tests were carried out and they gave the results of average optimum moisture content is 33.55%, maximum dry density is 1.34 g/cm3; cohesion c' = 75 Kpa and shearing resistance angle ϕ = 41°. Results of the tests were evaluated and slope stability and bearing capacity analysis were processed. An alignment was drawn using Autocad and the amount of earthwork was calculated. It was found that the ground is capable to build the proposed structure, however there is a need for 370.123 m3 fill earthwork. A strong recommendation was made to follow systems engineering approach in the construction phase, as well as the design stage. Dependability of the system is ensured by the good use of V – process of systems engineering. It is also recommended to undertake further testing including sulphate content and consolidation tests to confirm the validity of the design processed in this study.
