摘要：我们在场进有流动和静电干扰的破裂的化学 grouting 上的一系列试验性的测试流水，用透明破裂 grouting 试验性的设备。渗出物压力和薄泥浆繁殖的变化在我们的调查被比较。流动的水导致的结果表演渗出物压力落下，在繁殖区域的在上游的方面和落下的穿入半径的开发在一样的时期期间，与静态的水里的 grouting 相比。在薄泥浆到达联合边界以前，静态的水里的繁殖区域总是是圆的。然而，繁殖形状与流动的水为 grouting 从回合变成到椭圆形的形状破裂。为在就流动速度而言的破裂的薄泥浆穿入半径的一个理论模型被我们的试验性的结果开发并且验证。这些结果在改进破裂 grouting 机制并且在指导的理解是有用的设计惯例。

摘要：A highway distress and preventive measures decision support system based on WebGIS and J2EE architecture were studied, and the key issues for the system are presented. Such issues as spatial data and attribute data organization, technology of enhancing user experience, database connection pool were investigated. The feasibility of the theories and methods were tested through the system.
