水平定向钻进铺管地表工后沉降分析

Analysis of Surface Settlement Caused by Horizontal Directional Drilling after Pipeline Construction

水平定向钻进铺管不可避免地会导致地表产生沉降变形,且变形主要产生在铺管完成以后阶段,即地表工后沉降。本文基于随机介质理论,建立了适合于分析评价水平定向钻进铺管地表工后沉降变形的理论计算模型,并基于MATLAB GUI编写了相应的计算软件,能快速计算得到地表工后沉降的变形程度,可为水平定向钻进铺管设计及施工提供科学依据和指导。

Horizontal directional drilling inevitably causes surface settlement and the settlement usually occurs after pipeline construction.Based on stochastic medium theory,this paper builds a computational model to evaluate the surface settlement caused by horizontal directional drilling after pipeline construction and also compiles the calculation interface on the basis of MATLAB GUI platform.The model can calculate the settlement quickly,which provides guidance and reference for the design and construction of horizontal directional drilling in pipeline construction.
