采用GAP单元分析拱坝在静水压力作用下横缝中存在的各种间隙对坝体结构受力的影响，分析结果表明：横缝存在间隙对拱坝结构受力有不良影响；

An analysis by using the GAP element is performed to study the effects of different transverse joint 's gaps on the structural stresses of arch dam under static water pressure .

堰顶横缝表面封堵和混凝土裂缝的化学灌浆处理，增强了混凝土的防渗性能，坝体渗漏量降为1.88m3／h，满足了设计要求。

The impermeability of the concrete has been greatly improved and leakage of the dam body is decreased up to 1 . 88 m3 / h , thus meeting the design requirement .

大坝横缝在高程110m以下进行接缝灌浆，以增强大坝整体性和改善孔口应力；

The transverse joints under El . 110 m will be grouted in order to strengthen the integration of the dam and improve the stress state around the outlets .

计算结果表明，横缝下游宽度达到2mm以上，坝体应力恶化，将会危害到拱坝的安全。

The results show that when transverse joints aperture is beyond 2 mm , the development of transverse joints will change the structural action to a considerable extent , thus endangering the dam safety .
