Taking the traffic load as moving point load , the deformation characteristics of longitudinal section of pavement and composite foundation under moving point load are analyzed , considering the effect of pore pressure , traffic velocity , parameters of pavement structure and subgrade . finally , two examples of pavement section and soft subgrade , longitudinal section of airport runway and composite foundation are calculated 将交通荷载简化为移动的集中荷载，计算分析了单次移动加载和循环移动加载条件下道路纵截面与复合地基共同变形特交通荷载作用下道路与软土复合地基共同作用性状研究性，探讨了孔压、行车速度及道路结构层和地基参数对道路变形的影响。
Route 2 - a direct link between kwun tong and east kowloon via the airport tunnel underneath the old kai tak airport runway . this route extends westward and runs on the western kowloon corridor linking west and north - west kowloon with tsuen wan and tuen mun in the west . the trunk road extends further north from tuen mun to yuen long via the yuen long highway 二号干线-连接观塘及九龙东部的干道，途经旧机? ，然后向西伸延，经西九龙走廊，把西九龙和西北九龙与荃湾及屯门连接，并再由屯门经元朗公路向北伸展至元朗。
It has been applied largely to the highway pavements and the airport runways because of its excellent properties against tensile force , bending , cracking and etc . the influence of temperature ( low temperature , normal temperature and high temperature ) on the airport pavements quickly repaired by the sfrc is mainly studied in this paper so that we can satisfy the needs of the quick repair of the airport pavements better under different seasons 钢纤维混凝土是近年来发展起来的一种新型复合材料，它以其优越的抗拉、抗弯和阻裂等性能在公路路面和机场道面等工程中得到广泛应用。本文主要研究不同气温(低温、常温和高温)下钢纤维混凝土快速修补机场道面问题，以更好地满足不同季节机场道面快速修补的需要。
This subject directly investigates 14 construction enterprises and more than 40 construction sites . the types of the projects involve railway , bridges , tunnel , municipal , road , industry and civil construction , airport runway , hydraulic tunnel and others . this paper deeply analyzes and assesses the occupational health and safety management actuality of the construction site , points out the main problems in the process of hazard identification , risk assessment and risk control , and also analyzes why these problems exist 该课题研究直接调查了十四家施工企业和四十多个项目施工现场，项目类型涉及铁路工程、市政公用工程、公路工程、房屋建筑工程、机场场道工程、桥梁工程、水工隧洞工程、土石方工程等，对施工现场实际的职业健康安全管理现状进行深入的分析、评估，指出了危险源辨识、风险评价、风险控制过程存在的主要问题，并分析了为什么会存在这样的问题。
Finally , two examples show that , the availability and practicability of the new model is verified . the analysis of calculation result of berthiervill test embackment shows different part of compression curve have different influence upon the course of consolidation , and correct coefficient and viscous effect have great significance on deformation forecast . associated with the wenzhou airport runway engineering , the reason of increasing of pore - water pressuer in under - lying soft layer and post - construction settlement are given 最后，通过两个工程实例的分析来说明本文模型的有效性和实用性:一是对berthiervill填土试验场的软基实测数据和理论成果进行对比分析，阐明考虑结构性扰动和粘滞性效应对分析天然粘土固结压缩性的重要性;二是对温州机场袋装砂井超载预压工程进行数值模拟，指出停荷预压期间下卧层孔压增加和工后沉降大的原因。
And the results show that the calculated settlement agree well with that of measured . the paper established the dynamic pore pressure models of soft soil subgrade and composite foundation , compiled the dynamic fem program of undrained effective stress method , considering the elasto - plasticity of foundation soil as well as the interaction of pavement and foundation , thoroughly analyzed the deformation characteristics of pavement and foundation , and these results are instructive for the construction of pavement or airport runway 本文建立了软土地基和复合地基的动孔压经验模型，编制了不排水有效应力动力反应分析有限元程序，不仅考虑了地基土体的弹塑性，而且考虑了道路结构与地基的相互作用，比较全面地分析了交通荷载作用下道路与地基的整体变形特性，对道路工程或机场道面工程的建设具有一定的指导意义。
