Abstract Hypabyssal rock is a special material with the property between rock and soil. Few researches have been conducted on the mechanical properties of hypabyssal rock. In this study，a field test device for conducting the load carrying tests and the shearing tests simultaneously was designed. The load carrying test of fine sand hypabyssal rock and the shear test on cementation surface of concrete and fine sand-hypabyssal rock were conducted at the south anchorage base of Maputo bridge. The load carrying and shearing parameters of the fine sand-hypabyssal rock are obtained. Based on the obtained parameters，the prediction of deformation modulus of hypabyssal rock and the morphology and mechanism of shear failure of cementation surface were further studied and discussed. The bearing property of hypabyssal rock was found to be similar to rock. The empirical methods based on the on-site geological conditions can be used to estimate the deformation modulus accurately. However，the shear property of the cementation surface is different from the rock. Its low compactness leads to the strong cementation with the concrete and form an obvious adhesive zone. The cementation should be fully considered when the shear strength of the hypabyssal rock-concrete cementation surface is evaluated.

Key words： geotechnical engineering hypabyssal rock field experiment mechanical property deformation modulus cementation
