摘要
深圳东莞茅洲河界河段堤基广泛发育一层最新沉积的由淤泥、淤泥质粘性土组成的软土层,一般软土层具有天然含水量高、孔隙比大、压缩性高、承载力及抗剪强度低等不良工程地质特征,查明其埋藏条件和工程地质特征,结合本工程主要特点采用水泥搅拌桩、砼灌注桩、沉井方案等工程处理措施,对茅洲河界河段综合整治工程的设计和施工有着现实的意义。
Dyke foundation of Maozhou River is widely developed in the soft soil layer. Generally soft soil layer has bad engineering geological characteristics including natural high water content, void ratio, compression, bearing capacity and low shear strength. The paper identifies the burial conditions and engineering geological characteristics, takes the appro- priate engineering measures. It has a realistic significance of the design and construction of synthetical harnessing project of Maozhou River.
