深基坑工程施工的安全问题要控制风险的出现,就是要可靠的防止基坑整体失稳(滑坡和隆起),要防止支撑体系的强度破坏(支撑的偏心挠曲和撑点滑动),采取的对策:
(坚持按时空效应原理确定施工参数)
时空原理就是针对软土地层具有流变的特性,利用土在基坑开挖过程中位移的变化规律,提出的一种控制措施,具体地说对车站施工全过程按工序进行分解控制,在空间上规定尺寸大小,在时间上定下完成时限,按量化的空间和时间结合有序的操作.上海地铁一、二号线车站建设的实践证明,按时空效应原理施工是非常有效的积极的主动的安全施工措施.有了工程的安全,也就有了环境的安全,因此利用好时空效应的原理,才是根本的直接的环境保护措施.
1.2在监测数据指导下,按时空效应原理组织均衡的快速施工
快速施工是地下建筑安全施工的二大要素之一,快挖土、快支撑、快回筑,向“快”要安全.这种“‘陕,’是有序的“快”,是有准备的“快”,无序无准备的快是乱,乱要出乱子,该“快”不快也要出乱子.序就是按工序编制施工程序和操作细则,严洛按细则操作,做到有条不紊,分工明确、落实岗位、责任到人.工序施工准备就是要有超前的意识“做一、备二、想三”(根据能力、环境、天气).要做到有序有准备,事前要向全体施工人员进行施工方案的技术交底,这是关键也是先决条件,只有施工人员都明白了,做什么,为何要这样做,什么时间开始做,什么时间完,好的标准是什么,如何配合?分工明确、责任到人,就可以“快”起来.简言之,要使全体施工管理人员、工人建立起对深基坑工程施工要有尽快建立起新的永久平衡概念,有保护环境的风险意识,才会自觉的去“快干”,这是一项深基坑施十分重要的管理措施.

Deep Foundation works to control the safety of the emergence of risk is to prevent the foundation of reliable overall instability (landslides and uplift),it is necessary to prevent damage to the strength of support system (supported by eccentric deflection and sliding up the points),to take Countermeasures:
(Adhering to the principle of space-time effects to determine the construction parameters)
Space-time is the principle of land for the soft layer with rheological properties,the use of soil in the excavation process of change in the law of displacement,of a proposed control measures,specifically the construction of the station by the entire process of the decomposition process control,in space size of the provisions,in time to complete the time limit set by quantifying the spatial and temporal integration of the operations in an orderly manner.Shanghai subway,the station building on the 2nd line proves that space-time effect in accordance with the principle of construction is a very effective initiative a positive construction of the security measures.With the safety of the works,and will have a safe environment,so make good use of the principle of time-space effect is simply the direct environmental protection measures.
1.2,under the guidance of the monitoring data,in accordance with the principle of time-space effect of the rapid construction of balanced
Rapid Construction is the construction of underground construction safety,one of two elements,Fast excavators,fast support,built back to the "fast" to security.This " 'narrow,' is the order is" fast ",there is a preparation for a" fast "unprepared and disorderly fast is chaos,chaos to get into trouble,the" fast "unpleasant to get into trouble.Sequence is prepared by the process details of construction and operation procedures and strict rules of operation in accordance with carvedilol,so in an orderly,clear division of labor to implement posts of responsibility to the people.the construction process is the need to prepare in advance a sense of "do one or two prepared,like the three" (based on the capacity of the environment weather).to be prepared in an orderly manner,prior to all construction personnel交底construction technology program,which is also a key prerequisite for the construction personnel only understand what to do,how to do,why do so,What time does it start so,after what time,what is a good standard,how to cope with?a clear division of responsibility to the people,you can "speed up".In short,for all construction management personnel,workers established a deep foundation of construction must be established as soon as possible the concept of a new permanent balance,have the protection of the environment of risk awareness,conscious only to "drying",which is a deep foundation of facilities management is very important.
