中文拼音 [làngshímiàn]
浪蝕面
英文
abrasion surface-
Abraded bedrock surface
浪蝕基巖面Because of long - time water erosion and weathering, the furface of the stone becomes uneven, looking like a rough sea
由於長年被水流沖蝕溶蝕及風化作用,使巖石表面凸凹不平,如同風吹過水面,捲起千層浪。A time - variant reliability formulation is presented in this paper to account for the effects of fatigue, corrosion and maintenance actions on the first yield reliability of midship section modulus. a probabilistic model for long - term distribution of wave - induced fatigue stress range is established. for the purpose of obtaining the performance of structure that stands random fatigue load, the concept of stress parameter and equivalent stress range are introduced
船舶在由波浪彎矩引起的交變應力作用下,船體構件焊接點處的微小裂紋逐漸擴展;同時,隨著船齡的增加,眾多結構構件遭受腐蝕的作用;從而使船體梁剖面模數減小,船體梁承載能力衰減,船舶結構的安全性將受到相當大的影響。A safety reliability evaluation method for embankment slope stability under random storm wave actions and erosion - damage effects is proposed, the genetic algorithm has been used as the modern optimization technique applied to the minimization of the reliability index and the safety factor of embankment slope stability
文中針對隨機風浪作用下侵蝕-損傷的堤壩邊坡穩定性提出一種安全可靠性評價方法,應用遺傳演算法尋找最危險滑動面對應的安全系數和最小可靠指標,並與傳統優化演算法進行比較,遺傳演算法尋優結果穩定不依賴于初值,明顯優于傳統優化演算法。分享友人
