摘要
以印山越国王陵墓坑边坡加固为背景,通过试验比较几种化学材料的加固效果。在室内试验中,经过正硅酸乙酯加固的岩石试块效果相对较好:其外观状态改变最小,而单轴抗压强度和耐水性能有所提高,此外正硅酸乙酯的渗透性能也优于其他材料。在现场试验中,采用注射、滴注和喷淋等方式进行加固试验,结果表明正硅酸乙酯加固效果符合设计要求,可以作为墓坑边坡加固的化学材料之一。目前墓坑边坡加固已经完成,岩石表层强度有所增加,而碎石崩塌现象明显减小。
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.
