GEOTECHNICAL SURVEY OF STRATA CONDITIONS OF PESHAWAR REGION USING GIS

INTRODUCTION: The profiling and zoning of geotechnical sub-soil data is often considered as one of the very important information for the planning and a construction projects in civil engineering works. Data availability can cut the expense of the projects and also reduce time, particularly during feasibility and planning stage. In past few years, the numbers of construction projects in Peshawar have increased rapidly. Consequently, the number of soil boring reports has been accrued largely. The presentation of already available sub-soil data in a userfriendly format will enable the geo-technical and civil engineers beforehand to plan the detail geotechnical investigation based on the provided soil profile and STRATA MAPINGS (SMs). The SMs and sub-soil profile will facilitate the geotechnical engineers for preliminary design of foundations, feasibility study and preparation of rough cost estimates for the proposed projects. The geographic information system (GIS) is a valuable tool for geotechnical engineers, not only for non-data area prediction but also used to interpret the complex data area with reliability and accuracy.

LITERATURE REVIEW: Significant progress has been made in the field of geotechnical surveys in the past three decades of history of Peshawar. Government bodies such as National Surveying agency who carried out the geo referenced General Topographic Sheet (GTS) prepared by Survey of Pakistan in 1986 using a scale of 1:5000. Digital Elevation Model (DEM) of the Peshawar district at 10 m interval was created from the National Aeronautics and Space Administration, Shuttle Radar Topography Mission (SRTM) 90 m interval data for ascertaining the depth of the bore logs from the Natural Surface Level (NSL). Positions of Standard Penetration Test (SPT) soil samples were ascertained from Global Positioning System (GPS) readings and assigned to the corresponding 2 of 8

latitudes and longitudes. Using Inverse Distance Weighted (IDW) interpolating technique. The government of Khyber Pakhtunkhwa has initiated large scale public transportation projects in Peshawar in association of MOTT Macdonald Peshawar (MMP) with the sponsorship of Asian Development Bank (ADB). The Bus Rapid Transit Project, BRT Peshawar for short, was planned along one of the busiest routes of the city and at certain multiple positions boring holes were initiated toward depth of hard strata. Moreover, at every kilo-meter radius multiple tube well were installed reaching the available water tables, that gives us the review of the available water tables elevations and position along with the strata behaviour. Profiling and zoning of geotechnical sub-soil data using GIS has previously researched that barely is to the NSL level classifying soil and sand characteristics in the manner of zonings.

PROBLEM STATEMENT: In this research, the problems targeted are: ♦ The pre-prediction pre-arranging of the surveyed data organization in order to avoid future cumbersome preliminary surveys, which in turn will benefit us in saving time and a great save of finance, that is spent on surveys before any mega project initiation. ♦ Secondly, no detailed survey regarding Hard strata flow and the availability of the water table (positions and depth) has been done to the date. Like the incident in BRT Peshawar project of unexpected presence of the water table at the pile drilling process, at the location of Hastnagri chowk, Grand Trunk Road (GT. Road), resulting in financial loss and time.

OBJECTIVES: The research study is proposed to prepare ♦ Strata profile ♦ Strata Maps ♦ To furnish sufficient necessary reliable data regarding water table distribution, hard strata depths and bearing capacity of soils in the selected under study area of the Peshawar urban settlements. This research work will assist the geotechnical and civil engineers beforehand to plan the detail geotechnical investigation based on the provided strata profile and SMs.

METHODOLOGY: Phase 1 ♦ Data collection (Strata charts of tube wells, pile stratification data of all the mega projects of Peshawar) ♦ Organization and study of the collected data. ♦ GIS based determinations of Zones.

Phase 2 ♦ GIS based coordinates marking ♦ GIS based plotting of stratification on map to specify points of hard strata. ♦ GIS based plotting of water table distribution on map. ♦ Integrating all zones data regarding hard strata and water table depths and capacities

Phase 3 ♦ ♦ ♦ ♦

Universal mapping of the studied data of under study area. Animated demonstration of whole study and data. Presentation of 3D-model of the under-study area. Thesis drafting and finalization.

MANAGEMENT PLAN: This section presents the schedule, costs, and qualifications for completing the proposed research. To reach this goal, we will follow the schedule presented in Table 1.1:
