Abstract Taking the tomb pit slope at mausoleum site of Yue Kingdom in Yinshan for example,different chemical reinforcement materials are selected for the experimental study. In the laboratory test,the effect of specimens reinforced by tetraethyl orthosilicate(TEOS) shows relatively good:the appearance has the least change,the uniaxial compressive strength and water-resistance properties improve slightly;and the permeability of TEOS is better than that of others. In the field test,the TEOS is selected to reinforce rock by means of injecting,dripping and spraying. It indicates that TEOS meets the design requirements,so the TEOS can be used as one of the chemical materials for the tomb pit slope reinforcement. Now the reinforcement of the tomb pit slope is finished,the surface strength of rock slightly increases,and the case of rock fall decreases significantly.
