| Abstract | Long life along with higher performance, always desired from each construction facility,either vertical or horizontal structure. To fulfill these vital approaches in construction lifeline,it is extremely required to qualify the quality of construction material, do determine, andpredict the behavioral parameters of the bearing ground (bearing capacity and settlement).This research study, which predominantly confined to Kandahar city-Afghanistan, will brieflyillustrate the soil deposition, subsoil stratigraphy, engineering properties of subsoil, seismichazard, foundation types, and relation between foundation types and excavation depth.Kandahar city is bounded by: East Turnak River, West Arghandab River, South Dori riverand North some Igneous mountains and mountainous terrain with dimensions: East-West(Nasajee to Bagh-e-pul ) ( 26.29 KM) and North-South (Kotal-e-Murcha to Bala karaz) (10.58KM).Majority of the deposited soil is developed by flood plain of flowing water due to Turnak andArghandab Rivers which is mostly alluvial soil including some sandstone mountainous terrain.The subsoil stratigraphy and engineering properties illustrates that the north part of the city iswell-graded gravel and silty clay with low to medium plasticity, likewise the water table is atgreat depth.The active fault (nearby Chaman fault) and seismic hazard study is highlighting that the cityitself is not subjected to shallow earthquake (0-50 KM) hazard but the historical data says thatdeeper earthquakes with (100–250 KM) are pronouncedThe common foundation types with related excavation depth in Kandahar city are simple andshallow.Wall, Individual (Pad) and strip footings are common for residential and small commercialbuildings with direct proportion its excavation depth to the height of building, whereas Mat(Raft) foundation is common in multistory buildings, subjecting to commercial and publicutility purposes likewise deep pile foundations are applied for some highway bridge piers andabutments |
