摘   要 ：常規(guī)地基沉降變形預(yù)測方法在建立預(yù)測模型時，忽略了觀測數(shù)據(jù)列的隨機性影響，降低模型收斂 速度 ，導(dǎo)致預(yù)測準確度較低，因此，提出基于無人機測繪技術(shù)的高層建筑地基沉降變形灰線性預(yù)測方法。利用 無人機測繪技術(shù)采集地基平面圖數(shù)據(jù)并配準，校正偏移圖像，在此基礎(chǔ)上利用灰色理論構(gòu)建預(yù)測模型，通過累加觀測數(shù)據(jù) ，強化數(shù)據(jù)內(nèi)在規(guī)律，淡化觀測數(shù)據(jù)列的隨機性影響，加快模型收斂速度，并通過沉降變形數(shù)值擬 合曲線實現(xiàn)地基沉降變形預(yù)測。結(jié)果證明：所提方法對于預(yù)測地基沉降變形得到的預(yù)測準確度較高。

Absrtact: When establishing the prediction model, the conventional foundation deformation and settlement prediction method ignores the randomness of the observation data series, weak generalization ability of the model and poor prediction results, a gray linear prediction method for foundation settlement and deformation of high-rise buildings based on UAV mapping technology is proposed. The UAV surveying and mapping technology is used to collect the foundation image data, register and correct the offset image. On this basis, a gray prediction model is established. Through the accumulation of data, the inherent law of the data is strengthened, the randomness of the observation data column is weakened, the model convergence speed is accelerated, and the foundation settlement deformation prediction is achieved through the settlement deformation numerical fitting curve. The results show that the proposed method has a high prediction accuracy.

Keywords: UAV mapping technology; high rise building; foundation; deformation and settlement; prediction method
