【摘要】：立井建設(shè)安全監(jiān)測過程中,需要采用FLAC3D對立井建設(shè)中開挖的大硐室、硐室群等復(fù)雜結(jié)構(gòu)進(jìn)行安全性評估,但FLAC3D在模擬較復(fù)雜模型的情況下,建立三維網(wǎng)格模型的效率很低,建模時(shí)間長且難度大;基于軟件內(nèi)部單元節(jié)點(diǎn)生成規(guī)則,研究了2種軟件內(nèi)部單元節(jié)點(diǎn)編號順序并進(jìn)行了轉(zhuǎn)換,最終導(dǎo)出了FLAC3D可以識(shí)別的文檔并生成了實(shí)體單元和結(jié)構(gòu)單元。結(jié)果表明:這種三維建模方法可行,使原有費(fèi)時(shí)費(fèi)力的建模變的簡單快速,節(jié)約建模時(shí)間70%以上,對指導(dǎo)立井建設(shè)中的安全監(jiān)測項(xiàng)目有較大的價(jià)值。
[Abstract]:In the process of safety monitoring of shaft construction, it is necessary to use FLAC3D to evaluate the safety of large cavern, chamber group and other complex structures excavated in vertical shaft construction. However, when FLAC3D simulates more complex models, the efficiency of establishing 3D mesh model is very low. The modeling time is long and difficult. Based on the rules of generating internal unit nodes, two kinds of software internal unit node numbering order are studied and converted. Finally, the documents recognized by FLAC3D are derived and the entity unit and structure unit are generated. The results show that this 3D modeling method is feasible, makes the original time-consuming and laborious modeling simple and fast, saves more than 70% of modeling time, and has great value for guiding the safety monitoring project in shaft construction.
