Connecting with the practical situation of the liujialiang coal mine , this paper analyzes on the main factors influencing the construction progress of rock drivage , and advances some feasible measures for implementing the quick rock drivage 结合刘家梁煤矿的实际情况,分析了影响岩巷施工进度的主要因素,提出了实现岩巷快速掘进的一些可行措施。
Generally , no less than one compaction test is needed for any earth sample . when the sample has a little change , it is necessary to carry out another test , which would have great influence on construction schedule 一般一种土样至少需要做一个击实试验，土样稍有变化又需另作，从而给检测、监理人员造成较大负担，往往对施工进度有较大影响。
It becomes more and more a vital problem that how we can design and schedule reasonably in a soft soil engineering in the condition that certain work time and certain settlement after construction must be satisfied 如何在已定的工期内，在满足工后沉降的条件下，确定可靠的地基处理设计方案、合理计划施工进度，成为软基工程中迫切需要解决的重大课题。
( 4 ) the 3 - d finite element simulation model of yangchun mgo - mixed concrete is established ; meanwhile the correlative parameters boundary conditions and the simulation of construction rate are also studied by the numbers ( 4 )建立了阳春外掺mgo混凝土拱坝的三维有限元仿真模型，并对其计算分析的有关参数、边界条件以及施工进度的模拟等进行了系统研究。
In addition , retaining structure generally speaking made for the provisional proj ect , but the provisional how long time is still a fuzzy concept of the quality for the provisional engineering , it is closely related to construction speed actually 另外，深基坑支护结构一般情况下均做为临时性工程，但临时性为多久，仍然是一个模糊性的概念，与实际施工进度密切相关。
Unbounded partially prestressed reinforced ( ppc ) structure is a new form of reinforced concrete ( rc ) structure 5which need not set ducts , install tendons and grout in advance , so it is more convenient and quicken the rate of progress 无粘结部分预应力混凝土结构是一种新型的加筋混凝土结构形成，它不需要预留孔道、穿筋、灌浆等复杂工序，简便操作，加快了施工进度。
Abstract : a design and construction method to a new - typed cofferdam is introduced . after its project application , such advantages are proved as less investment , high construction pace , less labour power and dredging river 文摘:介绍一种新型围堰的设计施工方法.通过工程应用证明，新型围堰比采用传统的围堰不仅投资省，而且具有施工进度快、节省人力、不挖毁土地、疏浚河道等特点
In the end , an evaluation system has been developed according to the cascade analytical method in order to make a scientific evaluation to the construction scheme , the project scheduling and the layout system of the drawings 最后，本文利用层次分析法，开发了施工组织设计评价系统功能模块，从而对施工方案、施工进度计划和施工平面布置图的确定做一个科学的、量化的评价。
This database is the core of project management and information management , realizing data exchang among the scheduling system , the layout system of the drawings and the information management system on site 此外，本文还设计了工程项目数据库，作为工程项目管理和信息管理的核心，实现工程项目管理的各个模块，施工进度计划、施工平面布置图和施工现场信息管理之间数据的交互。
( 2 ) development and application of the light - type cable - stayed hanging - cradle for railway , the hanging - cradle was applied in the construction of large span railway prestressed continous beem bridge , the quality and schedule of the construction was ensured ( 2 )开发、应用铁路轻型斜拉式挂篮，施工大跨度铁路预应力混凝土连续梁，保证了工程质量，达到了最快6d浇筑t构一对梁段的施工进度。
