ОПТИМИЗАЦИЯ ПАРАМЕТРОВ СВАЙНО-АНКЕРНОЙ КОНСТРУКЦИИ В ГЛУБОКОМ КОТЛОВАНЕ Design parameters optimization of pile anchor support structure in a deep foundation pit of a substation

Rong Quan Fan, Wen Hui Zeng, Min Xia

Аннотация


Исследуются возможности оптимизации конструктивных параметров подпорной стенки с ограждением из буровых свай в котловане глубиной 24,6 м с восьмиярусным анкерным креплением в песчано-гравийном слое для строительства городской подстанции в Чэнду (Китай). Рассматривалось пять влияющих факторов, включая диаметры свай, расстояние между сваями, предварительное натяжение анкеров, угол наклона анкера и количество рядов анкерных тросов. В полевых условиях изучено деформационное поведение котлована и несущих конструкций, связанных с выемкой грунта, проведен геотехнический мониторинг. Предлагается инженерная схема оптимизации на основе технико-экономического сравнения вариантов с варьированием расчетных параметров для обеспечения безопасности и стабильности котлована, а также снижения затрат на строительство.
