【摘要】：隨著我國(guó)城市化進(jìn)程的大力推進(jìn),地產(chǎn)行業(yè)大力投資開(kāi)發(fā)建設(shè),各類高聳建筑物應(yīng)運(yùn)而生,在向更高發(fā)展的同時(shí)地下空間開(kāi)發(fā)也被受青睞,伴隨著地下空間大規(guī)模的開(kāi)挖,基坑支護(hù)安全穩(wěn)定性就顯得尤為重要。 本課題圍繞基坑支護(hù)穩(wěn)定性這一課題,從優(yōu)化基坑支護(hù)的設(shè)計(jì)方案到應(yīng)用FLAC3D進(jìn)行數(shù)值模擬穩(wěn)定性分析,對(duì)基坑可能產(chǎn)生失穩(wěn)的內(nèi)因、外因進(jìn)行探討分析。本次研究以探討基坑安全穩(wěn)定為主線,采用宏觀與微觀分析相結(jié)合,現(xiàn)場(chǎng)勘察與室內(nèi)分析并用,試驗(yàn)與模擬方法同步,多學(xué)科知識(shí)交叉綜合運(yùn)用,多種模式探討分析,理論聯(lián)系實(shí)踐等一系列研究方法,對(duì)基坑安全穩(wěn)定性進(jìn)行評(píng)價(jià)。 希望通過(guò)本課題的研究,給相關(guān)基坑安全穩(wěn)定問(wèn)題的研究分析提供參考借鑒,減少事故及安全隱患,增加經(jīng)濟(jì)效益,提高國(guó)民經(jīng)濟(jì),促進(jìn)基坑安全穩(wěn)定問(wèn)題研究的步伐。
[Abstract]:With the development of urbanization in our country, the real estate industry has invested heavily in the development and construction of various kinds of towering buildings, and the development of underground space has been favored along with the development of underground space, which is accompanied by the large-scale excavation of underground space. The safety and stability of foundation pit support is particularly important. This paper focuses on the stability of foundation pit support, from optimizing the design scheme of foundation pit support to using FLAC3D to analyze the stability of numerical simulation, the internal cause of the instability of foundation pit may be produced. The main line of this study is to discuss the safety and stability of foundation pit, the combination of macro and micro analysis, the combination of field investigation and indoor analysis, the synchronization of test and simulation, and the comprehensive application of multidisciplinary knowledge. The safety and stability of foundation pit are evaluated by a series of research methods, such as discussion and analysis of various modes, combination of theory and practice, etc. It is hoped that through the research of this subject, the research and analysis of the safety and stability of foundation pit will be provided with reference, reduce accidents and hidden dangers, increase economic benefits, improve the national economy, and promote the research of the safety and stability of foundation pit.
