| 摘 要： | 采用高压水射法对新老混凝土粘结面进行冲毛处理，粘结面的粗糙度以灌砂平均深度定量描述，以三种喷射水压力处理得到了不同粗糙度的粘结面，发现随着喷不压力的增大，粘结面的粗糙度增大，粘结劈拉强度提高。

| Abstract: | Water jet method is adopted in this paper to treat interface for adherence of young on old concrete. The interfacial roughness is described quantitatively with average depth of sand pour method. The different roughness of interface can be got with three kinds of water jet pressures. With the increase of water jet pressure, both the interfacial roughness and the splitting strength are improved. |
