?陜西省省級(jí)國(guó)有資本經(jīng)營(yíng)預(yù)算科技創(chuàng)新專項(xiàng)資金項(xiàng)目（ ZXZJ-2024-015）；陜西省重點(diǎn)研發(fā)計(jì)劃專項(xiàng)（2022LL-JB-10）摘要：
為解決復(fù)雜地質(zhì)條件下深基坑施工過程中因地質(zhì)不均、地下水滲流及外部荷載作用而引發(fā)的結(jié)構(gòu)失穩(wěn)等問題，提出了一種現(xiàn)場(chǎng)實(shí)測(cè)、數(shù)值模擬與數(shù)據(jù)分析相結(jié)合的深基坑多維監(jiān)測(cè)與動(dòng)態(tài)風(fēng)險(xiǎn)管理體系，對(duì)基坑水平位移、地表沉降、支撐內(nèi)力及地下水位等關(guān)鍵參數(shù)進(jìn)行實(shí)時(shí)采集與動(dòng)態(tài)評(píng)估，并建立基于監(jiān)測(cè)數(shù)據(jù)的分級(jí)預(yù)警與應(yīng)急響應(yīng)機(jī)制。結(jié)果表明，該體系能在一定程度上反映基坑變形發(fā)展趨勢(shì)及潛在風(fēng)險(xiǎn)特征，通過動(dòng)態(tài)調(diào)整支護(hù)措施和施工工序，可有效降低變形速率和沉降量，保證基坑整體穩(wěn)定，實(shí)現(xiàn)深基坑施工安全、高效、可控。

To address structural instability caused by geological heterogeneity, groundwater seepage, andexternal loading during deep foundation excavation construction in complex geological conditions, thispaper proposes a multidimensional monitoring and dynamic risk management system. The systemintegrates field measurements, numerical simulation, and data analysis, and incorporates a tiered earlywarning and emergency response mechanism based on real-time monitoring data. Key parametersmonitored include foundation excavation displacement, ground surface settlement, support internalforces, and groundwater levels. The results show that the proposed system can capture the developmenttrends of foundation excavation deformation and potential risk characteristics. By dynamically adjustingsupport measures and construction sequences, the system reduces deformation rates and settlement,thereby enhancing foundation excavation stability and realizing the safe, efficient and controllableconstruction of the deep foundation excavation.
