Abstract：Inorder to solve the problemsof landslide diseaseand soilerosion in power transmissionand transformationprojects，basalt fiber modified alkali wasused to stimulate foam concrete，and the volume content ofbasalt fiber was optimized by four indexes： concrete drying shrinkage value，water absorption，compressve strength and porosity，and then the slope treatment and anchoring process of power transmision and transformation project was studied based on the concrete.The results showed that 0.3% basalt fiber should be mixed into alkali-activated foam concrete，and the drying shrinkage value of concrete material was 64.1% of the benchmark concrete，the water absorption rate and compressive strength were the maximum，which were 31.08% and 7.26MPa ，respectively ，and the porosity was the smallest，only 57. 15% . The concrete has good water absorption performance，mechanical properties， drying shrinkage performance and pore structure properties，and is not prone to shrinkage cracking，which can improve the stabilityofthe slopeand has certain application value in the slope treatment and anchoring process of power transmission and transformation projects.

Key words：foam concrete；drying shrinkage；water absorption rate；basalt fiber；slope treatment
