针对目前钢绞线网片？聚合物砂浆加固技术中存在搭接，提出相向搭接和对扣搭接两种搭接方式，通过对拉试验研究这两种搭接方式的搭接锚固性能，包括搭接方式、钢绞线直径和涂抹聚合物砂浆。试验结果表明：1）采用配套铝扣锚固不会造成锚固位置钢绞线的局部损伤，所有试件的破坏位置均不在铝扣锚固位置；2）两种搭接方式均具有良好的搭接效果，但由于局部锚固导致钢绞线应力不均匀现象等影响，试件承载能力有10％～20％的损失量，因此，搭接位置应避开内力最大处；3）涂抹聚合物砂浆的试件和对扣搭接的试件钢绞线未出现相对滑移，而相向搭接试件出现一定的相对滑移。

For to the lap in the strengthening technique with strand mesh-polymer mortar,two kinds of lap jointing type are proposed,then the lap anchorage performance of these lap jointing types with different parameters are investigated, including lap jointing type,strand diameter and daubing polymer mortar.The test result shows:1)the aluminum anchor does not results in local damage of strand,no damage happens on anchorage position;2)two lap jointing types has good lap anchorage performance,but because of non-uniform stress,the bearing capacity decreases by 10%~20%,so the lap position would avoid the position with maximal internal force;3)the relative slip dies not occur in the test specimens of daubing polymer mortar and buckle lap,relative slap occurs in the test specimens of opposite lap.
