最优控制群桩扩张位移的安全度

Optimal Control the Safety of Expansion Displacement of Piles

本文主要通过最优控制理论来研究群桩沉击时挤压扩张位移的最优控制方案。在对综合性隔阻系数和安全度的规划后,可以有效地制订最佳的减弱和控制群桩扩张位移对相邻结构的破坏量实施方案,从而提高相邻结构的安全度。从文中工程实例的分析可以明显反映出所提供的最优控制群桩扩张位移方程的实用性、简便性,井具有一定的经济价值。

In this note,the optimal control theory is used in optimal control scheme of extrusion expansion displacement of driving piles. Having programmed the comprehensive segregated coefficient and the degree of safety , the implement scheme is effectively formulated to decrease and control the piles expansion displacement against the neighbouring structures. And then, the safety of the structures is improved. Some advantages, such as practicality, simplicity and economic benefit,of the present method are apparently shown by a given practical example.
