摘要

在活动地裂缝影响下,供水管道拉裂、错断现象时有发生,并引发严重的次生灾害。本文以西安市西南郊水厂拟建球墨铸铁管道穿越地裂缝为工程背景,建立管道45°穿越活动地裂缝的数值模型,分析地裂缝影响下管道的内力响应与变形特征,结果表明:地裂缝作用会使管道接口偏转角过大而导致其防水失效。因此提出一种分段管廊装载供水管道穿越地裂缝的方法,建立分段管廊装载供水管道穿越地裂缝的数值模型,分析管道与管廊通缝、错缝两种工况、不同分段管廊长度、不同地裂缝位置、不同穿越角度下管廊与管道的内力响应与变形特征。得出管廊装载管道穿越地裂缝的最佳方案为管道与管廊通缝布设,采用单节长度为18 m的分段管廊,使地裂缝位于管廊的2/3处,并尽量以小角度穿越地裂缝。研究成果对城市供水管道穿越活动地裂缝的工程建设与灾害防治具有实际意义。

Abstract

Under the influences of active ground fissures, the cracking and dislocation of feed pipeline occur from time to time, and cause serious secondary disasters. Based on the engineering background of the proposed ductile iron pipeline crossing the ground fissure in the Southwest Suburb Water Plant of Xi'an City, this paper establishes a numerical model of the 45° pipeline crossing the active ground fissure, and analyzes the internal force response and deformation characteristics of the pipeline under the influence of the ground fissure. The results show that the ground fissure will cause the deflection angle of the pipeline interface to be too large and cause its waterproof failure. Therefore, a method of sectional pipe gallery loading water supply pipeline through ground fissures is proposed, and a numerical model of sectional pipe gallery loading feed pipeline through ground fissures is established. The internal force response and deformation characteristics of utility tunnel and feed pipeline under two working conditions of joint and staggered joint between feed pipeline and utility tunnel, different length of sectional utility tunnel, different locations of ground fissures and different crossing angles are analyzed. It is concluded that the best scheme for utility tunnel loading feed pipeline through ground fissures is the layout of joint between utility tunnel and feed pipeline. The sectional utility tunnel with a single section length of 18 m is adopted to make the ground fissure located at 2/3 of the utility tunnel and cross the ground fissure at a small angle as far as possible. The research results have certain practical significance for engineering construction and disaster prevention of urban feed pipeline crossing active ground fissures.
