【摘要】：地下管线是城市基础设施的重要组成部分。国家每年要投入大量的财政资源来修建和维护城市地下管线。综合管廊,是将燃气、电力、电信、给水、雨水、污水乃至垃圾等各种不同的管道,共同敷设在一个地下空间中的市政管道的设置方案。随着城市的发展,管道截面的要求在不断增加,地下管道修建的复杂性也在增加,使综合管廊的修建日益复杂。由于地下施工的特殊性及施工环境的不确定性,使得隧道施工复杂性大增。同时,由于隧道施工中可以用空间有限,各种施工活动需要共享有限的空间以及有限的设备。由于隧道施工过程中各种不可预见的因素,精确的施工效率仿真极具挑战性。基于仿真平台,决策者可以快速检验多种施工方案的可行性,从而避免了昂贵的实地检验。为了深入了解施工过程,并在此基础上进行资源优化、减少延误,本文采用基于离散事件仿真(DiscreteEvent Simulation)的方法模拟施工过程,对项目施工效率及工期进行评估。基于对隧道施工过程的深入了解,本文编制一套基于SYMPHONY仿真平台的盾构作业仿真模型。该模型包括盾构过程中开挖、衬砌、测量等过程。同时,为了克服在不同地质条件下施工进度不同的问题,本文通过一组实测数据,获得了盾构机在不同类型岩土环境下的施工进度。
[Abstract]:Underground pipeline is an important part of urban infrastructure. The country spends a lot of financial resources every year to build and maintain urban underground pipelines. The integrated pipe gallery is the installation scheme of the municipal pipeline which lays gas, electricity, telecommunication, water supply, Rain Water, sewage and even garbage together in one underground space. With the development of the city, the requirements of pipeline section are increasing, and the complexity of underground pipeline construction is increasing, which makes the construction of integrated pipe corridor increasingly complex. Because of the particularity of underground construction and the uncertainty of construction environment, the complexity of tunnel construction is greatly increased. At the same time, due to the limited space available in tunnel construction, all kinds of construction activities need to share limited space and limited equipment. Due to various unpredictable factors during tunnel construction, accurate simulation of construction efficiency is challenging. Based on the simulation platform, decision-makers can quickly test the feasibility of various construction schemes, thus avoiding expensive field inspection. In order to understand the construction process, optimize the resources and reduce the delay, this paper simulates the construction process based on discrete event simulation, and evaluates the construction efficiency and duration of the project. Based on the deep understanding of tunnel construction process, a simulation model of shield operation based on SYMPHONY simulation platform is developed in this paper. The model includes excavation, lining, measurement and so on. At the same time, in order to overcome the problem of different construction progress under different geological conditions, this paper obtains the construction progress of shield machine under different types of geotechnical environment through a set of measured data.
