摘　　要：广珠西线高速公路实测沉降表明,沉降速率与剩余沉降基本为线性关系,沉降速率与剩余沉降的平方基本为正比关系,进而从理论上论证了两者的关系。两者的这种关系有利于将工后沉降法、沉降速率法统一起来。It is proven by monitored settlement of Guangzhou -Zhuhai West Expressway that settlement velocity is proportional to residual settlement and is in direct proportion to the square of residual settlement. The above conclusion is proven by theory deduction too. The relationship between settlement velocity and residual settlement is useful for harmonizing method of post - construction settlement with method of settlement velocity.

关 键 词：沉降速率 工后沉降 剩余沉降 双曲线
