饱和松散地层沉陷区路桥工程治理关键技术

Key Control Technologies of Road and Bridge Engineering in Subsidence Area With Saturated Loose Layer

摘要: 赵固二矿地表塌陷区治理具有饱和地表松散层、表土层巨厚、煤层开采厚度大的特点，造成地表塌陷量较大、路桥加固难度大等诸多困难。利用理论分析和数值模拟对不同采厚条件下的饱和松散地层的沉陷规律及地表路桥加固方案进行了研究，实现了饱和松散地层沉陷区的桥梁加固，能够满足沉陷区大幅度不均匀沉降的特殊要求。

Abstract: The control in surface subsidence area of Zhaogu No.2 Mine has characteristics of saturated surface loose layer, thick alluvium, thickness of coal seam mining, which causes many difficulties such as large surface subsidence, hard road and bridge reinforcement. The laws of mining subsidence and the reinforcement scheme for road and bridge are studied under differnent mining thickness by using theoretical analysis and numerical simulation. The reinforcement for road and bridge in subsidence area with saturated loose layer is achieved, which can meet the special requirements of significant differential settlement in subsidence area.
