為指導鄭西鐵路客運專線做好施工期間的沉降觀測，通過對路基、橋梁及隧道工程的沉降觀測資料進行分析，預測工后沉降，提出加速路基沉降的措施，確定無碴軌道的鋪設時間，評估路基工后沉降控制效果，確保無碴軌道結(jié)構(gòu)的安全，制定本指導方案。In order to direct ZhengXi PDL to do well settlement observation during construction, establish this directing scheme by analyzing settlement observation data of subgrades, bridges, and tunnels, forecasting settlement after construction, raising accelerating subgrade settlement measurement, confirming the time of paving slabtrack, evaluating the controlling effect of subgrade settlement after construction, making sure safety of slabtrack structure. 無碴軌道鋪設條件評估的重點應是線下工程的變形，評估應綜合考慮沿線路方向各種結(jié)構(gòu)物間的變形關系，以標段為單位實施。設計單位按照本指導方案，以標段為單位制定沉降觀測實施設計方案。Evaluation keypoints of slabtrack paving conditions should be deformation of underline construction. Evaluation should synthetically consider deformation relation among different structures along alienment, implement by section. Contractors should establish settlement observation implement design scheme by section according to this scheme. 基礎工程的沉降觀測數(shù)據(jù)必須采用先進、成熟、科學的檢測手段取得，且必須真實可靠，全面反映工程實際狀況。Settlement observation data of foundation engineering should be gott
