【摘要】：隨著建筑事業(yè)的迅速發(fā)展,我國(guó)各地的建筑行業(yè)也迎來(lái)了發(fā)展的新勢(shì)頭。于此同時(shí),國(guó)家在面對(duì)這樣好的發(fā)展的同時(shí),也對(duì)我們國(guó)家建筑行業(yè)的發(fā)展提出來(lái)了更加嚴(yán)格的要求。尤其是深基坑工程的發(fā)展,由于基坑施工技術(shù)難度過(guò)大或者受各種地質(zhì)條件的影響因素,可能會(huì)造成實(shí)際的施工與數(shù)值模擬出現(xiàn)很多局限性。這就要求我們?cè)诠こ淌┕さ倪^(guò)程中做好同步的監(jiān)測(cè),達(dá)到安全要求。同時(shí)對(duì)建筑的質(zhì)量品質(zhì)、標(biāo)準(zhǔn)、工業(yè)化提出了更高的要求。在現(xiàn)在的社會(huì)對(duì)我國(guó)建筑行業(yè)的發(fā)展提出了龐大的需求,因此,國(guó)家和政府部門應(yīng)該對(duì)我國(guó)的建筑行業(yè)加強(qiáng)監(jiān)管的力度,以此來(lái)確保我國(guó)建筑行業(yè)的發(fā)展。深基坑工程在施工過(guò)程中經(jīng)常事故突發(fā),多部分原因是基坑支護(hù)結(jié)構(gòu)的原因造成的。論文從下方面對(duì)深基坑工程支護(hù)方案選取及安全性進(jìn)行評(píng)估:(1)在收集資料和查找文獻(xiàn)的基礎(chǔ)上,了解現(xiàn)在深基坑工程在基坑設(shè)計(jì)和開(kāi)挖支護(hù)方面可能存在的問(wèn)題,為了保證基坑工程的安全穩(wěn)定性,對(duì)基坑工程在開(kāi)挖時(shí)的監(jiān)測(cè)進(jìn)行分析,提出自己的看法。(2)采用FLAC3D軟件對(duì)基坑工程在開(kāi)挖和支護(hù)進(jìn)行數(shù)值模擬,將模擬后所得到的結(jié)果與實(shí)際監(jiān)測(cè)的結(jié)果作比較分析。在對(duì)比結(jié)果分析可以看出數(shù)值模擬與工程實(shí)際提供的監(jiān)測(cè)資料是基本可以相吻合的,偏差在允許范圍內(nèi)。可以看出對(duì)基坑開(kāi)挖支護(hù)FLAC數(shù)值模擬具有較好的參考價(jià)值。(3)文中對(duì)選取的濰坊市某工程深基坑實(shí)例的工程概況和周邊環(huán)境做了詳細(xì)介紹,然后根據(jù)工程地質(zhì)條件和工程的使用要求以及要達(dá)到的經(jīng)濟(jì)性和安全性等方面考慮,對(duì)基坑工程的支護(hù)設(shè)計(jì)選取適合的方案。
[Abstract]:With the rapid development of the construction industry, the construction industry in various parts of our country also ushered in a new momentum of development. At the same time, the country in the face of such a good development, but also put forward more stringent requirements for the development of our national construction industry. Especially the development of deep foundation pit engineering, because the construction technology of foundation pit is difficult to pass large or affected by various geological conditions, may cause a lot of limitations in actual construction and numerical simulation. This requires us to do a good job in the construction process of synchronous monitoring, to achieve safety requirements. At the same time, the quality of the building quality, standards, industrialization put forward higher requirements. In the present society, there is a huge demand for the development of the construction industry in our country. Therefore, the state and government departments should strengthen the supervision of the construction industry in order to ensure the development of the construction industry in our country. During the construction of deep foundation pit, accidents often occur, and many reasons are caused by the supporting structure of foundation pit. This paper evaluates the selection and safety of deep foundation pit engineering support scheme from the following aspects: (1) on the basis of collecting data and searching literature, we know the possible problems existing in deep foundation pit design and excavation support. In order to ensure the safety and stability of foundation pit engineering, the monitoring of foundation pit engineering during excavation is analyzed, and its own views are put forward. (2) numerical simulation of excavation and support is carried out by using FLAC3D software. The results obtained by simulation are compared with those of actual monitoring. The comparison results show that the numerical simulation is basically consistent with the monitoring data provided by the engineering, and the deviation is within the allowable range. It can be seen that FLAC numerical simulation of excavation and support of foundation pit has good reference value. (3) in this paper, the engineering situation and surrounding environment of a selected deep foundation pit in Weifang City are introduced in detail. Then according to the engineering geological conditions and the requirements of engineering use as well as the economy and safety to be achieved the appropriate scheme is selected for the supporting design of foundation pit engineering.
