通过 Plaxis 有限元计算程序模拟内撑式排桩支护基坑的开挖，分别研究了开挖深度、软土模量、软土厚度、桩长、桩间距等因素对邻桩变形和内力的影响，分析研究表明，基坑开挖时，邻桩侧移和内力受软土模量、软土厚度、开挖深度、桩间距和刚度等因素的影响，所以应综合考虑多种因素的影响，将对邻桩的影响降至安全范围内。
通過 Plaxis 有限元計算程序模擬內撐式排樁支護基坑的開挖，分彆研究瞭開挖深度、軟土模量、軟土厚度、樁長、樁間距等因素對鄰樁變形和內力的影響，分析研究錶明，基坑開挖時，鄰樁側移和內力受軟土模量、軟土厚度、開挖深度、樁間距和剛度等因素的影響，所以應綜閤攷慮多種因素的影響，將對鄰樁的影響降至安全範圍內。

Numeric simulate cantilever row piles excavation used the finite element software Plaxis. Analyze the influences of depth of excavation, the elastic modulus and depth of soft clay,the length and the distance between piles and distance from excavation face on deformation and stress. The analysis shows that the deformation and stress for the nearby pile was influenced by the elastic modulus,the depth of soft clay,the depth of excavation and the distance between piles when foundation excavation. Therefore,in the excavation,should be taken into account the influence of various to minimize the influence on adjacent pile.
