【摘要】：目前我國己經(jīng)建成并開通了武廣、鄭西、京滬等多條高速鐵路和城際客運專線,初步構(gòu)建了高速鐵路網(wǎng)。為了快速疏散客流,按照我國目前交通領(lǐng)域“零換乘”的規(guī)劃設(shè)計理念,大中型城市高鐵車站地下往往還連接一條或多條城市地鐵連接在一起,形成現(xiàn)代化的交通樞紐。 城市地鐵線路由于種種原因,往往落后于高速鐵路鐵路建設(shè),不能同步投入運行。這樣就必然導(dǎo)致車站附近地鐵施工會穿越已經(jīng)開通運營高速鐵路線路的情況。在城市附近,為節(jié)約用地,普遍采用以橋代路的策略,導(dǎo)致地鐵隧道需要從鐵路橋梁基礎(chǔ)附近穿越。在地鐵隧道施工過程中可能對鄰近高鐵橋梁基礎(chǔ)產(chǎn)生擾動,導(dǎo)致高鐵橋墩產(chǎn)生平面位移、傾斜及沉降等變形,而高速鐵路無砟軌道對基礎(chǔ)穩(wěn)定性要求非常高,為確保高鐵安全運營和結(jié)構(gòu)安全,對地鐵施工影響范圍內(nèi)的高鐵橋梁基礎(chǔ)變形進行監(jiān)測非常必要。 論文研究結(jié)合南京地鐵6號線穿越京滬高速橋梁和寧安沉降鐵路橋梁的實際情況,構(gòu)建了采用測量機器人、傾斜傳感器與靜力水準儀等多種現(xiàn)代監(jiān)測設(shè)備和傳感器的監(jiān)測方案,對高速鐵路橋墩的平面位移、傾斜和沉降等幾個方面的變形進行監(jiān)測,采用卡爾曼濾波法對實時監(jiān)測的傾斜和沉降監(jiān)測數(shù)據(jù)進行處理,有效地降低了監(jiān)測數(shù)據(jù)的噪音。對各個不同類型的監(jiān)測數(shù)據(jù)之間得到的橋墩變形規(guī)律進行對比,變化趨勢一致,變化量稍有差異。 根據(jù)監(jiān)測數(shù)據(jù)的綜合分析,確定了寧安城際5#橋梁基礎(chǔ)附近隔離防護樁試樁施工期間的變形規(guī)律,確定了隔離防護樁的有效性；確定了京滬高速鐵路橋梁基礎(chǔ)附近隔離防護樁施工期間、盾構(gòu)隧道穿越期間和穿越之后不同施工階段的橋梁基礎(chǔ)的變形規(guī)律,分析了不同階段變形與對應(yīng)工況之間的關(guān)聯(lián)。 監(jiān)測結(jié)果表明監(jiān)測系統(tǒng)的有效性,客觀反映了不同施工工況下高速鐵路橋梁橋墩的平面位移、傾斜和沉降變化情況,為高速鐵路安全運營和地鐵旋工安全防護決策提供了客觀的數(shù)據(jù),研究結(jié)論對其他類似工程具有一定的參考價值。
[Abstract]:At present, our country has built and opened several high-speed railways, such as Wuguang, Zhengxi, Beijing-Shanghai, and inter-city passenger dedicated lines, and has preliminarily constructed a high-speed railway network. According to the planning and design concept of "zero transfer" in the field of transportation in our country, underground high-speed railway stations in large and medium-sized cities are often connected with one or more urban subways to form a modern transportation hub. Urban subway lines, for various reasons, often lag behind the construction of high-speed railways and cannot be put into operation at the same time. This will inevitably lead to subway construction near stations passing through the situation where high-speed railway lines have already been opened. In the vicinity of the city, In order to save land, the strategy of substituting bridges for roads is widely adopted, which leads to the subway tunnel crossing from the railway bridge foundation. During the construction of the subway tunnel, it may disturb the foundation of the adjacent high-speed railway bridge, resulting in the plane displacement of the piers of the high-speed railway. In order to ensure the safety operation and structural safety of high-speed railway, it is necessary to monitor the deformation of high-speed railway bridge foundation in the influence area of subway construction. According to the actual situation of Nanjing Metro Line 6 crossing Beijing-Shanghai high-speed bridge and Ningan subsidence railway bridge, the paper constructs a measuring robot. A variety of modern monitoring equipment and sensor monitoring schemes, such as tilt sensor and static level, are used to monitor the plane displacement, tilt and settlement of piers in high-speed railway. Kalman filter method is used to deal with the monitoring data of tilt and settlement in real time monitoring, which can effectively reduce the noise of monitoring data. The deformation law of bridge pier obtained from different types of monitoring data is compared, and the change trend is consistent. The amount of change varies slightly. According to the comprehensive analysis of monitoring data, the deformation law of isolated protective pile near the foundation of Ningan Intercity Bridge is determined, and the effectiveness of isolated protective pile is determined. The deformation law of the bridge foundation during the construction of isolated protective piles near the bridge foundation of Beijing-Shanghai high-speed railway, during and after the passage of shield tunnel is determined, and the relationship between the deformation of different stages and the corresponding working conditions is analyzed. The monitoring results show that the effectiveness of the monitoring system objectively reflects the changes of plane displacement, tilt and settlement of bridge piers of high-speed railway under different construction conditions. It provides the objective data for the safety operation of high-speed railway and the decision-making of the safety protection of metro rotary workers. The conclusion of the study has certain reference value for other similar projects.
