Abstract

Reinforced soil structure test sections have been constructed along the alignment of the highway route no 1149 leading to the top of a mountain in Chiang Rai Province, northern Thailand. The test sections are located on the steep slope of residual soil derived from diorite, divided into two subsections for a total length 9f about 300 m. Their heights vary up to twelve meters. The face slope is 70 degrees, initially protected with soil bags and finally with grasses and creepers. The reinforced element is high tensile strength polymer grid composing of "Tensar" SR 55, SR 80 and SR 110. Subsurface drainage is provided using artificial band drain to prevent built-up pore water pressure during the rainy season. Performance of the test sections is checked by visual inspection as well as records from instrumentations, i.e., inclinometers, piezometers, the settlement plates. The performance after the first rainy season is quite satisfactory.

Reinforced Soil Structure Test Sections in Mountainous Terrain

St. Louis, Missouri

Reinforced soil structure test sections have been constructed along the alignment of the highway route no 1149 leading to the top of a mountain in Chiang Rai Province, northern Thailand. The test sections are located on the steep slope of residual soil derived from diorite, divided into two subsections for a total length 9f about 300 m. Their heights vary up to twelve meters. The face slope is 70 degrees, initially protected with soil bags and finally with grasses and creepers. The reinforced element is high tensile strength polymer grid composing of "Tensar" SR 55, SR 80 and SR 110. Subsurface drainage is provided using artificial band drain to prevent built-up pore water pressure during the rainy season. Performance of the test sections is checked by visual inspection as well as records from instrumentations, i.e., inclinometers, piezometers, the settlement plates. The performance after the first rainy season is quite satisfactory.
