The geotechnical evaluation of the proposed Teeb dam site at Missan governorate

الملخص EN

The standard Penetration Test (SPT) results are used to describe and evaluate the consistency of cohesive soils and the compactness of the non-cohesive soils of Teeb dam site.

This hydraulic structure located on Teeb river at the north east of Missan governorate is proposed to collect and regulate flood water of winter season and groundwater recharge.

The SPT results are also used to calculate the relative density and the angle of internal friction after correcting the N- values.

Relative density values range between 38- 96 % and internal angle of friction range between 27.65- 45º.

The bearing capacity of beds in the proposed Teeb dam site is classified according to SPT value to four main beds, very stiff silty clay, medium dense poorly graded sand , dense poorly graded gravel and very dense poorly graded gravel mixed with sand.
