应用不同的约束混凝土强度理论，对混凝土井壁的竖向极限承载能力进行了计算分析，通过与试验结果的比较，认为进行混凝土井壁的竖向极限承戴能力计算采用Ｏｔｔｏｓｅｎ准则和Ｐｏｄｇｏｒｓｋｉ准则较合适，为计算方便和精确，又对各种在等值侧压条件下混凝土破坏准则进行了分析，最后利用试验结果，建立了一个形式简单、物理概念明确的混凝土井壁破坏准则，从而得到了该种井壁的竖向极限承载能力计算公式，可供设计时采用。

补充资料：混凝土桩
用混凝土与钢筋或钢丝制成的桩。具有节约木材和钢材、经久耐用、造价低廉等优点，已广泛使用于水工建筑、工业建筑、民用建筑和桥梁的基础工程。混凝土桩分为普通钢筋混凝土桩和预应力混凝土桩两类。桩的截面有方形、矩形、八角形、圆形和环形等，最常用的是方形截面桩和环形截面桩。方形截面桩的边长和环形截面桩的外径为20～60厘米。桩的长度可达40米，上端设置桩帽，下端设有桩尖。混凝土桩的制作工艺基本上与混凝土电杆相同。
