Description
本发明涉及疏浚工程技术领域，特别是涉及一种复杂地质沉管隧道基槽分土质超欠挖分析方法及装置。
目前，疏浚工程主要采用断面法分析基槽超欠挖(超欠挖包括超挖和欠挖)，原理为事先根据基槽施工平面图、施工纵横断面图垂直于基槽中心线绘制足够数量的测线，以保证计算精度；利用设计数据与实测水深数据的标高差值制作二维色差图，利用色差图的色块与标高差值二维平面分析基槽欠挖厚度与超挖深度，利用纵横剖面图分析基槽局部的欠挖厚度与超挖深度。
其中，断面法适用于航道疏浚、基槽开挖、道路、河堤等狭长带状线性工程的土方量计算，分析开挖质量；原理为划分场地为若干平行的横截面，假定相邻断面之间均匀变化，计算每相邻断面间土方量，各断面间土方量之和为总土方量，本质上是一种简化模型。断面法步骤清晰直观，可核查超深、超宽的土方量，中间资料完整性较好，可得到每个特定桩号的断面图，利用断面图可直观分析施工质量，提供详细的土方量计算结果报告；但效率较低，计算过程复杂，可视化效果差，对于大面积复杂区域和计算区域随时变化的情况，误差较大。
因此，采用断面法分析基槽超欠挖存在以下不足：(1)对于中心线为不规则三维空间曲线、设计纵横断面边坡点多等设计结构复杂的基槽、航道，为保证计算精度，需沿基槽、航道三维中心线绘制大量测线，重复性工作量大且精
度低。(2)无法分析基槽欠挖区域的土质，为后续欠挖区域开挖提供量化依据。(3)平面分析与断面分析独立，无法实时联动，每一次断面分析需重新设定参数，重复工作量大，操作相对复杂。(4)二维分析，可视化效果差。
发明内容
基于此，有必要针对采用断面法分析基槽超欠挖存在的不足，提供一种复杂地质沉管隧道基槽分土质超欠挖分析方法及装置。

分别建立基槽的基槽开挖模型和基槽地质模型；
切割所述基槽地质模型，以建立基槽欠挖地质模型和基槽超挖地质模型；
