L9 (34) orthogonal experiment was adopted, the effects of concentration of initiator, reaction time, volume ratio of monomers and amount of PVA on shear strength of adhesive were investigated.

The results indicate that cement mixing ratio, water content and comparative effort have important influence on shear strength, compressibility and microstructure of the compacted cement -loess.

The formula of reduced shear strength coefficient of RC beams with inclined cracks is put forward to according to the test data.
