確定了船體梁整體破壞時的剖面應力分佈之後,關鍵在於確定板架的極限屈曲強度。本文充分考慮了在縱向彎曲、橫向壓力作用下加筋板可能發生的幾種破壞模式,即板架的整體屈曲破壞、樑柱形式的破壞、筋的側傾、腹板的屈曲並同時考慮了初始焊接殘余應力、初撓度的影響,使其更精確的計算加筋板的屈曲強度。對于加筋板中加強筋腹板的局部屈曲,採用解析法推導出筋的腹板的撓度方程及其邊界條件,求解相應的方程,從而計算出腹板的局部屈曲應力。Surrounding these special problems met in gas hydrates exploration and through study of high - precision magnetic survey, the sea test by r / v haiyang 1y that is owned by guangzhou marine geological survey in dongsha area of the south china sea, systematical analysis of the test result and combination interpretation of magnetic survey with seismic profile, the authors successfully employ the method to recognize the truth or false of the diapir in seismic profile by integrating total field of high - precision marine magnetic measurement with its gradient change
