自2003年三峡水库蓄水以来，茅坪溪防护工程泄水洞水库下压段渗水问题、洞室稳定性问题备受业主、勘测设计等单位的重视，经多次对茅坪溪防护工程泄水洞水库下压段渗水点进行观测，通过动态预测分析，三峡水库蓄水后，在不同的工况条件下运行，渗水点渗水量具有蓄水后不但没有增大，反而随着蓄水时间的推移，渗水量有逐渐减小的特征，验证了前期勘测成果的正确性，也为结晶岩渗漏问题、洞室稳定研究提供了翔实的资料。
自2003年三峽水庫蓄水以來，茅坪溪防護工程洩水洞水庫下壓段滲水問題、洞室穩定性問題備受業主、勘測設計等單位的重視，經多次對茅坪溪防護工程洩水洞水庫下壓段滲水點進行觀測，通過動態預測分析，三峽水庫蓄水後，在不同的工況條件下運行，滲水點滲水量具有蓄水後不但沒有增大，反而隨著蓄水時間的推移，滲水量有逐漸減小的特徵，驗證瞭前期勘測成果的正確性，也為結晶巖滲漏問題、洞室穩定研究提供瞭翔實的資料。

Since the Three Gorges reservoir impounding in 2003,the underpart water penetration and cavern stability problems of Xieshuidong Reservoir in Maopingxi have been paid much attention by owners ,surveying and designing companies ,so the leakage points of the underpart were observed many times .Through the dynamic prediction and analysis ,it was found that the leakage quantity of points did not increase when the reservoir operated in different conditions after the impoundment of the Three Gorges reservoir ,instead the quantity decrease gradually with the storage time .It is proved that early investigation results are correct ,which provides informative data for the prevention of water penetration in crystalline rock and cavern stability .
