问题包括排水管被堵、地基下沉，有时甚至出现了严重的结构性裂缝。
Problems include blocked drains, sunken foundations and, sometimes, large structural faults.
实践证明，聚丙烯纤维对防止混凝土早期非结构性裂缝具有较好的效果。
By practice, polypropylene concrete has good effect in preventing non-structure crack.
采取合理的坝体变形控制措施，合理的分缝和结构型式是改善超高混凝土面板堆石坝面板应力状态，避免或减少面板产生结构性裂缝的关键所在。
The deformation control and suitable joint plan are the key to improve the stress behavior of the concrete face and are also the key to avoid or reduce the rupture of the concrete face.
通过对某高桩码头横梁裂缝深度的超声检测、骑缝取芯验证，说明对于活荷载引起的结构性裂缝，由于卸载后裂缝重新闭合，超声法检测存在局限性。
The ultrasonic method is unfit for inspecting the depth of crack originated from live load, since the crack will close after the load is removed.
早期裂缝对路面使用性能不会产生明显影响。然而，裂缝的扩展最终会导致沥青路面结构性破坏。
Early cracks don't obviously effect the using properties of the pavement, but the enlarging will result in the structural damage to asphalt concrete pavement.
