Bamboo is a kind of high strength and environmental protection building materials that can be used to solve the problems of high cost for both traditional shallow excavation supported and the temporary structure removed. The bamboo pile bending test and the single row bamboo micro-piles model tests were put foreword. The results show that the elastic modulus of bamboo pile decreases gradually with increase of the net cross-sectional area in the bending test; the elastic modulus is mainly distributed in 8.0-12.5 GPa. In model test

the strain of pile increases gradually up to peak with the increase of the depth and then gradually decays to 0. The reverse strain appears after reaching 0; and then the reverse strain decays to 0 after reaching the peak. According to the results of strain of pile and displacement of pile top

the use of single row bamboo micro-piles can get better support effect in the support of shallow foundation pit. The research results would provide experimental basis for studying the supporting mechanism of the single row bamboo piles and provide a reference for engineering design as well.
